How To Record Piano

Piano is one of the most acoustically complex instruments you can put in front of a microphone. Unlike a guitar or a vocal, a piano produces sound from dozens of strings simultaneously, radiates in multiple directions at once, and interacts with every surface in the room. Done right, a well-recorded piano sits in a mix with weight, warmth, and presence. Done wrong, it sounds boxy, muddy, or thin — and no amount of plugin processing will fully fix a bad source recording.

This guide covers everything from choosing and placing microphones on an acoustic grand or upright, to recording electronic and hybrid pianos, to the DAW workflow that keeps your sessions clean and flexible. Whether you are tracking a solo classical piece, adding a piano bed to a pop production, or building a sample library, the techniques here apply. Updated May 2026.

Understanding the Piano as a Recording Subject

Before you place a single microphone, spend five minutes understanding how a piano actually produces and radiates sound. This knowledge directly informs every placement decision you will make.

How Sound Leaves the Piano Body

When a hammer strikes a string, the string vibrates and transfers energy through the bridge to the soundboard — a large, slightly curved wooden panel that acts as the primary radiator. On a grand piano, the soundboard faces downward and the lid above reflects sound upward and outward. On an upright, the soundboard faces the wall behind the piano, which is why uprights often sound better when pulled 18–24 inches away from the wall.

Different frequency ranges leave the piano from different locations. Bass strings are long and occupy the left side of the piano (from the player's perspective). Treble strings are short and occupy the right side. The midrange sits between them. When you place a single microphone in one position, you are inevitably emphasizing one tonal region. Stereo placement corrects this by capturing a panoramic view of the entire string array.

The piano also produces a significant amount of mechanical noise: key action, hammer shanks, damper felts, pedal noise, and even the player's bench. High-sensitivity condenser microphones pick up all of this. Knowing this in advance helps you plan your setup to minimize unwanted noise without sacrificing the natural character of the instrument.

Room Acoustics and Why They Matter More for Piano Than Almost Any Other Instrument

A piano in an acoustically dead room sounds like a piano in a cardboard box. The instrument was designed to project into a space and interact with its environment. Conversely, a room with too much reverb and flutter echo will make your recording sound like it was recorded in a bathroom.

If you are serious about piano recording, read our detailed guide on home studio acoustic treatment before you commit to a room. For piano specifically, you want enough natural ambience to give the recording life — typically a RT60 (reverberation time) of 0.3–0.8 seconds for a solo classical recording, and even less for a tight pop/R&B context where the piano will sit in a dense mix. Rooms with hardwood floors, high ceilings, and non-parallel walls tend to sound best. If your room is overly dead, you can add room ambience in post with reverb plugins. If it is too live, baffles and gobos around the piano can tame it.

Microphone Selection for Piano

The right microphone choice depends on your budget, the type of piano, and the sonic character you are after. Here is a breakdown of the major categories and specific recommendations that work well in real sessions.

Large-Diaphragm Condensers

Large-diaphragm condensers (LDCs) are the most common choice for solo or classical piano recording. They capture detail, air, and the full harmonic spectrum of the instrument beautifully. The AKG C414 in its various configurations is an industry standard — it has been on piano recordings in top studios for decades. The C414 XLII variant has a slightly brighter character that works well on grand piano, while the C414 XLS has a flatter response that is better for upright pianos or situations where you want a more neutral capture.

The AKG C414 in cardioid or wide cardioid pattern is a natural starting point. For budget-conscious setups, the Rode NT1 (5th generation) gives excellent results on piano at a fraction of flagship microphone prices. On the higher end, Neumann U87s, U184s, and KM184s are all proven tools used in professional piano recording worldwide.

Small-Diaphragm Condensers

Small-diaphragm condensers (SDCs) offer a tighter, more precise transient response and a more consistent polar pattern across the frequency range. This consistency matters a lot in stereo pair applications, where matched patterns are critical for accurate imaging. Neumann KM184s, DPA 4006s, and Schoeps CMC6/MK4 capsules are gold-standard SDC options for piano recording in orchestral and classical contexts.

In a home studio context, the Rode M5 matched pair offers surprisingly good results on piano for its price. The Oktava MK-012, when carefully matched, also performs well. SDCs tend to sound more transparent and analytical, while LDCs add a subtle warmth and character. Neither is universally better — it depends on the musical context.

Ribbon Microphones

Ribbons are less common on piano but worth knowing about. A ribbon microphone in figure-8 pattern placed in a Blumlein configuration gives a beautifully natural, mid-forward stereo image that works especially well for intimate jazz or classical recordings. The Royer R-121 and Coles 4038 are the classic choices. Ribbons are figure-8 by nature, which means they pick up the room from both front and back — only use them if your room sounds good.

Pattern Selection

For most stereo piano recording situations, cardioid or wide cardioid patterns are the safest starting point because they reject sound from behind (the room), giving you more control over the blend of direct and ambient sound. Omni patterns capture a more natural, open sound with no proximity effect, but they also capture everything in the room — use them only if the room is part of the sound you want. Hypercardioid patterns give tighter rejection and are useful when you need to isolate the piano in a live room with other instruments playing simultaneously.

Microphone Placement Techniques

Microphone placement is where piano recording goes from science to art. There are established techniques that provide reliable starting points, and then there is the careful listening and adjustment that separates a good recording from a great one.

ORTF Stereo — The Workhorse Technique

ORTF (Office de Radiodiffusion-Télévision Française) is a near-coincident stereo technique where two cardioid microphones are spaced 17 centimeters apart (capsule to capsule) at an angle of 110 degrees between them. This approximates the distance and angle of the human ears, which produces a stereo image that feels natural and realistic when played back through speakers.

For grand piano, position the ORTF pair 6–12 inches above the strings, roughly over the mid-to-treble range of the keyboard — around the midpoint of the string array, which is typically above the damper rail. Point the pair slightly toward the bass side to balance the tonal weight. Aim for the microphone capsules to be above the area where the hammers strike (slightly toward the player), not directly above the tail end of the piano.

ORTF gives you a stable, phase-coherent stereo image that collapses well to mono — critical for broadcast and streaming contexts. It is the most versatile starting point for piano recording and works well in a variety of room sizes.

Spaced Pair (A/B) — Wide and Immersive

Two microphones spaced several feet apart (typically 3–6 feet on a grand piano, covering the full width of the string array) produce a wider stereo image with more room ambience. The trade-off is that spaced pairs are more susceptible to phase problems when summed to mono, because the distance between capsules creates time delay.

Inside a grand piano with the lid open, a common approach is to place one mic approximately 6–8 inches above the bass strings and one mic 6–8 inches above the treble strings, both at the same height. This gives you full tonal coverage and a wide, open stereo field. It works beautifully for solo piano recordings, singer-songwriter albums, and any context where mono compatibility is less critical.

Always check mono compatibility on a spaced pair setup before committing to it. In your DAW, sum both channels to mono and listen for frequency cancellations or a thin, hollow sound. If you hear significant issues, adjust the spacing or try moving both mics closer together.

XY Coincident Pair — Phase-Perfect and Precise

XY is the most phase-coherent stereo technique because the two capsules are placed as close together as physically possible (capsule-to-capsule), angled at 90–135 degrees. Because there is zero time difference between the capsules (only level differences from the angled pattern), XY is perfectly mono-compatible and works well in productions where the piano needs to translate cleanly across multiple playback systems.

The limitation of XY is a narrower stereo image compared to ORTF or spaced pair. On a grand piano, this can make the recording feel slightly centered and less expansive. XY is ideal when the piano is one element of a dense mix (pop, R&B, film score) rather than a featured solo instrument.

Blumlein Pair — Natural and Room-Capturing

The Blumlein configuration uses two figure-8 pattern microphones (or bidirectional ribbons) at 90 degrees, capsules coincident. It captures sound from front and back simultaneously, which means it captures a lot of room. In a good room, Blumlein sounds extraordinary — natural, three-dimensional, and open. In a bad room, it captures everything wrong about the space. Use it only when the room is part of the sound you want.

Close-Miking Techniques for Pop and Film Contexts

In pop, R&B, and film music sessions, the piano is often recorded much more closely to achieve a drier, more controlled sound. Common placements include one or two mics placed 3–6 inches above the hammers (capturing attack and transient detail), combined with one or two mics further back toward the tail of the piano capturing body and sustain. These two positions can be blended in your DAW to shape the tone from punchy and bright to full and warm.

A popular close-mic technique in Nashville and LA pop sessions is the "over-the-hammers" pair: two condensers (often SDCs like KM184s) in ORTF or near-ORTF configuration, placed 4–6 inches above the hammer rail, facing down toward the strings. This gives a bright, present, articulate sound that cuts through busy arrangements. Combine it with a distant pair for a blendable texture.

Upright Piano Placement

Upright pianos present different challenges. The soundboard faces the wall, the top can be opened, and the front panel (if removable) exposes the lower strings and damper mechanism. Common approaches include:

• Over the top: With the lid open, place two microphones above the top opening, angled downward. This is the most accessible position and gives a balanced sound.
• Front panel off: Remove the bottom panel and place one mic facing the lower soundboard and one mic over the top opening. Blend to taste.
• Behind the piano: Pull the upright 18–24 inches from the wall and place microphones facing the back of the soundboard. This gives a more full-range, direct capture but limits the room contribution.
• Room mic only: For a vintage or lo-fi aesthetic, a single room microphone 6–10 feet in front of the upright can capture an impressionistic, ambient piano sound with natural room character.

Signal Chain and Gain Staging

Getting a clean signal chain from piano microphone to DAW is non-negotiable. Piano has a very wide dynamic range — from whisper-quiet pianissimo passages to thunderous forte chords — which means gain staging requires more care than with most other instruments.

Audio Interface Selection

You need an audio interface with at least two high-quality microphone preamps, 48V phantom power, and enough headroom for transient peaks. For home studio piano recording, the Focusrite Scarlett 4i4 is a capable entry-level option. For more demanding sessions, the Universal Audio Apollo Twin X, Apogee Quartet, or SSL 2+ provide noticeably better preamp quality that shows up clearly on detailed instruments like piano. See our best audio interfaces roundup for current recommendations across price tiers.

If you are using ribbon microphones, verify that your interface's preamps have adequate gain (at least 60dB) and that the phantom power can be independently disabled per channel — applying 48V phantom power to an unbalanced ribbon can damage the ribbon element.

Setting Gain Correctly

Piano's dynamic range is the biggest technical challenge. Have the pianist play the loudest passage they expect to perform — the climax of the piece, the hardest chords — while you watch the input meters. Set gain so those peaks hit no higher than -12 to -10 dBFS on your interface's meters. This leaves headroom for unexpected dynamic spikes and avoids converter clipping.

For quieter, intimate piano recordings (soft jazz, ambient, neo-classical), you may need more gain and will therefore have more self-noise from the preamps and microphones. This is where the quality of your signal chain becomes most audible. A high-noise preamp on a quiet piano passage creates a continuous hiss underneath the performance that is very difficult to remove convincingly.

Using High-Pass Filters at the Preamp Stage

Most professional microphone preamps and many audio interfaces include a high-pass filter switch, typically set at 80Hz or 100Hz. For piano recording, be cautious about engaging this at the preamp stage — piano has legitimate musical content well below 80Hz in the bass register (the lowest note on a standard 88-key piano, A0, is 27.5Hz). Only use the preamp high-pass filter if you are dealing with severe low-frequency rumble from HVAC systems or building vibration, and even then, use the lowest cutoff point available. You can always apply EQ in post; you cannot recover cut frequencies.

Using Compression During Tracking

Many engineers choose to record piano without any compression, preserving full dynamic range for mixing decisions later. This is generally the safest approach. However, in pop sessions where the piano will sit in a dense mix, light compression during tracking (a 2:1 ratio, slow attack of 30–50ms to let transients through, medium release of 100–300ms, gain reduction of 2–4dB) can help tame unpredictable peaks and make the gain structure more manageable.

Never print heavy compression to the recorded file without keeping a dry (uncompressed) track as a backup. Use your DAW's input monitoring to audition compressed sound during tracking, but record the dry signal to disk. Understanding how to use compression correctly gives you far more flexibility in the mixing stage.

Sample Rate and Bit Depth

For piano recording, 24-bit depth is essential — it provides far greater dynamic range than 16-bit (144dB theoretical vs 96dB), which matters significantly for an instrument with this much dynamic variation. Sample rate is more debatable. 48kHz is the minimum for any professional work, and 96kHz is worth using for solo piano or orchestral recordings where you want to capture the full harmonic overtone series and give yourself more flexibility if you plan to pitch-shift or time-stretch in post. 192kHz offers diminishing returns and creates very large file sizes, but some mastering engineers and purists prefer it for archival classical recordings.

Recording Digital and Hybrid Pianos

Not every producer or engineer has access to a concert grand. Many home studios use digital stage pianos, weighted MIDI keyboard controllers with software instruments, or hybrid acoustic/digital systems. Each requires a different approach.

Stage Pianos and Digital Pianos via Direct Output

Most stage pianos (Yamaha CP88, Roland RD-2000, Nord Stage 4) have balanced stereo line outputs. Connect these directly to your audio interface using balanced TRS or XLR cables. Set the piano's output level to unity gain (0dB or maximum clean output) and adjust gain at the interface. Direct line-level signals from digital pianos are already clean and noise-free, so gain staging here is straightforward: aim for peaks around -12 to -6 dBFS with plenty of headroom.

The limitation of direct recording is that you miss the acoustic character of the piano cabinet and its interaction with the room. If this matters for your production, consider a hybrid approach: record the direct output simultaneously with one or two room microphones placed 3–6 feet in front of the piano cabinet's speakers. Blend the two signals in your DAW — the direct gives you clarity and detail, the room microphones give you space and character.

MIDI Controller + Software Piano

For producers working with software pianos (Pianoteq 8, Modartt instruments, Native Instruments The Grandeur, Spitfire Audio LABS Piano, East West Steinway), the recording chain is different. You are recording MIDI data rather than audio, which you later route through a virtual instrument plugin to render as audio.

The critical technical point here is MIDI velocity response. Your software piano's realism depends entirely on how accurately it maps MIDI velocity values to the dynamics of a real piano performance. Spend time calibrating your MIDI keyboard's velocity curve to match how you actually play. Most DAWs let you apply a velocity curve transformation (linear, exponential, logarithmic) to incoming MIDI. A harder velocity curve makes the piano more responsive to aggressive playing; a softer curve helps tame a heavy touch for delicate passages.

Record MIDI and a simultaneous audio render (if your software instrument allows real-time bounce) so you have both to work with. This workflow is discussed in depth in our guide to using MIDI in your DAW.

Pedal Tracking and Expression

Sustain pedal (MIDI CC64), soft pedal (MIDI CC67), and sostenuto pedal (MIDI CC66) data should always be recorded alongside MIDI note data. Many producers forget to arm the CC lane recording or use a footswitch that only sends on/off values rather than continuous values. For realistic piano performance in software instruments, make sure your sustain pedal sends consistent values (127 for fully pressed, 0 for released) with no bounce or double-triggers — a common issue with cheap sustain pedals. Test your pedal before tracking an important session by monitoring MIDI input in your DAW.

Latency Management for Live Performance Recording

When recording a MIDI keyboard performance through a software instrument in real time, latency (the delay between pressing a key and hearing the sound) must be low enough that the performer is not affected. Most pianists can tolerate up to about 10ms of round-trip latency; anything above 12–15ms becomes noticeably disorienting. Set your DAW's buffer size to 64 or 128 samples during recording (increasing to 512 or 1024 during mixing to reduce CPU load). At 48kHz, a 128-sample buffer gives approximately 2.7ms of buffer latency before you add your interface's hardware latency overhead.

DAW Workflow and Session Setup

A clean session setup before you record saves you hours of confusion in the mixing stage. Here is a professional approach to organizing a piano recording session in any major DAW.

Track Layout and Naming

Create individual mono or stereo tracks for each microphone position. Name them clearly: "Piano L (ORTF Bass)", "Piano R (ORTF Treble)", "Piano Room L", "Piano Room R", "Piano Close Over Hammers". Color-code all piano tracks the same color. Create a bus or folder track labeled "Piano" and route all individual piano tracks into it. This lets you control the overall piano level with one fader and apply bus processing (compression, EQ, saturation) as a group.

Always record to individual tracks rather than a pre-mixed stereo bus during tracking. Even if you plan to deliver a simple stereo piano track in the final mix, having the individual microphone signals on separate tracks gives you the flexibility to re-balance, phase-align, or completely replace any single element later.

Phase Alignment

When you use multiple microphones at different distances from the piano, the signals will arrive at each capsule at slightly different times. This time offset creates phase relationships that can cause frequency cancellations when the tracks are summed together. In your DAW, zoom in to the waveforms on all piano tracks and align the transients of the first attack (on a sharp, percussive note) so they are perfectly synchronized.

Some DAWs include automatic phase alignment tools (Logic Pro's Sample Accurate Timing, Studio One's Track Transform). Third-party plugins like Sound Radix Auto-Align Post can do this automatically and with sample-accurate precision. For manually aligned tracks, use the track delay or track nudge feature in your DAW to shift tracks by individual samples until the waveform peaks align. After alignment, flip the polarity on one track and listen — if the combined sound gets thinner, your alignment is correct. Flip polarity back and you should hear the tracks add constructively.

Editing Piano Takes

Classical and jazz piano recordings often require minimal editing — the performance should be captured as-is. Pop and commercial sessions frequently involve comping multiple takes, pitch correction (on acoustic piano, this means selective replacement of badly tuned notes, which is rare but possible), and timing nudges.

For comping, record multiple passes of the same section, then create a comp track by selecting the best phrases from each take. In Logic Pro, use Quick Swipe Comping on a Take Folder. In Ableton, stack takes in clip slots and record alternate performances in session view. In Pro Tools, use Playlist Comping mode. The approach differs slightly by DAW but the concept is identical.

If subtle timing adjustments are needed on a piano performance, use your DAW's elastic audio or flex time carefully and sparingly. Piano transients are sharp and clear, which means time-stretching artifacts are more audible than on softer instruments. Keep stretches under ±50ms where possible. For larger corrections, it is almost always better to re-record than to heavily time-stretch piano audio.

Tuning Considerations

Acoustic pianos go out of tune. A piano that has not been tuned recently may be sharp or flat in specific registers, or may have individual notes that do not stay in tune with the rest. Before any important recording session, have the piano professionally tuned — ideally 24 hours before the session, giving the strings time to settle after the tuning stress. If the piano has not been tuned in over a year, it may require multiple tuning passes over several days to bring it back to correct pitch without the strings slipping again immediately.

Check the tuning again on the day of the session with a chromatic tuner or a tuning app (PianoMeter is excellent) before rolling tape. If the piano is even 5–10 cents sharp or flat overall, let the performer know before they start, and note the offset in your session file so that any software instruments or overdubs can be tuned to match.

Monitoring During the Session

Use a quality pair of headphones or studio monitors for monitoring during the piano recording session. The challenge of monitoring piano is that the acoustic sound bleeds into the control room — you will always hear a mix of the acoustic piano and the recorded signal simultaneously, which makes it hard to evaluate the true sound of your recording. If possible, monitor in a separate room from the piano, or use closed-back headphones and a screen between you and the instrument.

Reference your piano recording on multiple speaker systems during and after the session: your primary studio monitors, headphones, a small Bluetooth speaker, and even a phone speaker if the music is destined for streaming. Piano in a mix needs to translate across all of these contexts, which means checking on reference studio monitors as well as consumer playback devices is part of the professional workflow.

Mixing and Processing the Piano Recording

Once you have clean, well-recorded piano tracks in your DAW, the mixing stage is where you shape the final sound. Piano rarely needs dramatic processing — the goal is usually to enhance what was captured, not to fundamentally change it.

EQ Approaches for Piano

High-pass filtering is the first step on any piano track that sits in a dense mix. Use a gentle 6dB/octave or 12dB/octave high-pass at 40–60Hz to remove low-frequency rumble and inaudible sub energy that wastes headroom. For a solo piano recording, keep the high-pass as low as possible (30–40Hz) to preserve the full bass register.

Common problem areas and their EQ solutions:

• Muddiness around 200–350Hz: A narrow cut of 2–4dB at the offending frequency cleans up the low-mid buildup that plagues room recordings.
• Boxy, enclosed sound around 400–600Hz: Again, a narrow parametric cut. This is common when recording uprights with mics placed inside the cabinet.
• Honky or nasal midrange around 800Hz–1.2kHz: A gentle cut helps if the room or mic placement has emphasized this range.
• Brightness and presence around 2–5kHz: A gentle boost here adds presence and helps the piano cut through a mix. Use a wide shelf or low-Q bell for a natural sound.
• Air above 12kHz: A gentle high shelf boost (1–2dB) adds sparkle and openness. Great for classical or pop piano that needs to breathe.

Use a high-quality EQ plugin for piano. The FabFilter Pro-Q 3 is the industry standard for surgical precision and natural-sounding cuts and boosts on complex material like piano. For a more analog-colored character, plugins that emulate classic hardware EQs (API 550, Pultec EQP-1A) can add warmth and musicality to digital piano recordings.

Compression on Piano

Compression on piano is always a compromise between controlling dynamics and preserving the expressive arc of the performance. A few guidelines:

Solo piano: Often no compression, or a very gentle optical-style compressor at 2:1 with a slow attack (50–100ms) and auto-release to gently catch the loudest peaks without audibly squashing the dynamics. The Tube-Tech CL 1B plugin emulation is excellent for this transparent, musical compression character.

Pop/R&B mix context: More compression is appropriate here to help the piano sit consistently in the mix. A VCA-style compressor (SSL G Bus Comp character) at 4:1, faster attack (10–20ms), medium release (100–200ms), and 4–6dB of gain reduction keeps the piano even and controlled without killing its dynamics entirely.

Parallel compression: An excellent technique for piano. Print a heavily compressed version of the piano (10–15dB of gain reduction, fast attack and release) and blend it at low level underneath the uncompressed track. This adds body and sustain without audibly compressing the transients. Many engineers route piano to a dedicated parallel compression bus for exactly this purpose.

Reverb and Spatial Processing

Piano and reverb are deeply intertwined in recorded music. The approach depends entirely on the musical context:

Classical/solo: Use a high-quality algorithmic or convolution reverb that emulates a real concert hall. Lexicon 480L-style reverb, Valhalla Room, or Altiverb with a real hall impulse response. Pre-delay of 20–40ms lets the direct piano signal establish itself before the reverb bloom, maintaining clarity. Reverb time (RT60) of 1.5–2.5 seconds for a classical context.

Pop/R&B: Shorter room-style reverb (0.4–0.8 seconds) or a plate reverb character. A plate reverb on piano gives it a warm, smooth tail that blends well in dense mixes. Use a send effect rather than inserting reverb directly on the piano track, which gives you level control independently and allows multiple instruments to share the same reverb space. See our guide on how to use reverb in a mix for detailed send routing techniques.

Lo-fi/ambient: Heavy reverb with long pre-delay, or even a shimmer reverb for ethereal piano textures. Stacking multiple reverb units (a room reverb plus a plate plus a large hall) can create layered spatial environments that work well in ambient and neo-soul contexts.

Stereo Width and Imaging

If you recorded in stereo with well-placed microphones, the stereo width is already baked into the recording. Avoid over-processing stereo width with widening plugins — they introduce phase issues and often cause the piano to collapse strangely on mono playback. Instead, use panning and balance adjustments between your multi-microphone tracks to control the width naturally.

For mono-recorded or direct-recorded piano that needs width, a doubling technique using a short stereo delay (10–30ms left, 15–35ms right) or a chorus effect at low depth can create an artificial stereo spread. Another technique is to process the mid and side signals independently with a mid-side EQ: boost the sides' high frequencies slightly for width, cut the sides' low frequencies to keep bass mono and centered.

Saturation and Harmonic Enhancement

Tape saturation plugins or tube saturation can add warmth and harmonic complexity to digital piano recordings that sound overly clean. Use saturation sparingly — 1–3dB of gentle even-harmonic saturation (tape machine style) adds body without sounding distorted. Plugins like Waves J37, UAD Ampex ATR-102, or iZotope DDLY (for tape-style delay coloration) are worth exploring. Saturation is particularly effective on digital piano recordings that lack the natural harmonic complexity of a real instrument.

Advanced Techniques and Special Recording Scenarios

Recording Piano in a Live Band Context

Recording piano simultaneously with a live band (drums, bass, guitar) presents bleed challenges. Any microphone on the piano will pick up drums and other loud instruments, making it difficult to edit or process the piano independently in the mix.

Solutions include: using directional (cardioid or hypercardioid) microphones angled away from the drum kit; placing a sound baffle or gobo between the piano and the drums; recording the piano with a direct output (if digital) or using a piano direct box on the acoustic piano's built-in microphone/pickup system if equipped; or recording the piano to a separate overdub pass after the live basic tracks are laid down. Each approach has trade-offs between performance energy and technical control.

Prepared Piano Recording

Prepared piano — where objects (bolts, rubber erasers, felt strips, paper) are placed on or between strings to alter the timbre — is a technique associated with John Cage and widely used in experimental, film score, and ambient music. Recording prepared piano benefits from close microphone placement (3–5 inches above affected strings) to capture the buzzes, scrapes, and modified resonances clearly. An SDC with a figure-8 pattern pointed parallel to the affected strings can capture an unusually detailed and intimate sound. Start with close placement and add room mics for ambience as needed.

Multi-Mic Blending — Building a Composite Sound

Professional piano recording almost always uses three or more microphone positions blended in the mix: a close pair over the strings, a mid-distance pair capturing the full body of the instrument in the room, and one or more room microphones further back. This multi-layer approach gives you a composite piano sound that has both detail and depth — close mics provide attack and definition, mid-distance mics provide body and natural balance, and room mics provide space and life.

When blending, start with the mid-distance pair as your primary level and add the close mics until you hear enough attack and presence. Then add room mics to taste until the piano feels like it is in a space. A common mistake is using too much close mic and too little room, resulting in a piano sound that is too bright, toppy, and lacking in natural body.

Recording Piano for Sample Libraries

If you are building a custom piano sample library or contributing to a commercial sample pack, the technical demands are significantly higher. You will typically record each note individually (or in groups of 3–4 semitones) at multiple velocity layers (typically 4–8 layers per note), multiple round-robin variations, and multiple articulations (sustained, staccato, con sordino with soft pedal, etc.).

This requires a highly consistent room and setup — every note must be recorded with the same microphone positions, the same gain structure, and the same acoustic environment. Room treatment is critical. Use the best microphones and preamps you have access to. Organize your session with careful file naming conventions (e.g., "A3_v7_rr2" for A3, velocity layer 7, round-robin variation 2) because you will end up with thousands of individual audio files that must be meticulously organized.

Noise Reduction and Cleanup

Even in the best sessions, piano recordings capture mechanical noise: pedal squeaks, bench creaks, finger noise, HVAC rumble, or electrical interference. iZotope RX provides the most comprehensive set of tools for addressing these issues — the Spectral Repair module can surgically remove squeaks and clicks in the frequency domain without affecting the surrounding piano sound. The Noise Reduction module can reduce low-level HVAC noise found in the gaps between notes.

For pedal noise specifically, if the piano's damper pedal squeaks, you can often physically treat it with a small amount of appropriate lubricant before the session. This is far better than trying to remove pedal squeaks in post-production after the fact.

Stereo to Mono Translation — A Final Check

Before you declare a piano recording finished and move to mix, always sum it to mono and listen critically. Pop out one of your stereo monitors or use your DAW's mono check button. Listen for: frequency cancellations (thin or hollow sound), significant level changes (the piano should not get dramatically louder or quieter in mono), and loss of clarity or definition. If you hear problems, the issue is almost certainly phase — check your microphone polarity, phase alignment between tracks, or stereo width processing plugins.

A piano recording that sounds great in stereo but falls apart in mono will cause problems in broadcast, DJ systems, Bluetooth speakers, and any other mono-adjacent playback system. Many streaming services process audio through algorithms that check mono compatibility, and a problematic piano track can catch their attention. Understanding how to make music that translates on any system is fundamental to professional piano production work.
