Basic piano recording techniques
Hello!
So you want to record your piano performances? Great!
Recording is so rewarding but it’s also unforgiving and frustrating. It lets you send songs to your friends, your family, and the entire internet, and it lets you enter the world of recorded music sales. It also lets you preserve all of your performance mistakes in high fidelity, forever, for all to hear.
Nervous yet?
Your first few recordings will be kind of atrocious. They’ll finally let you hear what your piano teacher has been telling you (maybe for years) but that you’ve never really internalized because it’s very hard to listen critically while playing at your limit. Use that new-found ability to concentrate solely on listening, figure out what you’re doing wrong, and get good!
Don’t get hung up on expecting perfection though; a perfect recording is rarely made in one take. Professional recordings are collages consisting of multiple takes, multiple overdubs, and even pieces of notes. Think extreme Photoshop but for audio. Automated tools exist for both tempo and pitch correction – take a look at Antares Auto-Tune or Logic Pro’s Flex Time.
Lower your standards to start and get some recordings done. Remember, a final draft is still a draft; it’s just that someone decided it wasn’t worthwhile to keep making changes.
Then work on your skills and raise your standards over time.
Good luck!

A map
This document will introduce several basic ways to record digital and acoustic pianos.
This document is a map and is not an exhaustive step-by-step guide. If knowledge can be assumed (e.g. how to play the piano or how to click the mouse on the computer) I’ve omitted it. If information is well documented somewhere else (e.g. in a user manual), I’ll direct you to that place. Instead, I’ll provide a way to connect the dots between those types of information.

Audio vs. MIDI
An audio file contains the sounds that you hear.
A MIDI file contains no sounds of its own and instead contains commands that instruct an instrument how it should play sounds (note on, note off, pedal down, pedal up, etc.).
As MIDI is a huge world unto itself and doesn’t allow one-step recording of the sound of a performance, I’ll focus on plain-old audio here.
Types of audio files
Audio files that you download or stream are compressed to save bandwidth and storage space. Some degradation in quality occurs with typical “lossy” compression techniques such as MP3 or AAC. As a result, some pianos will record uncompressed WAV files with no associated degradation. Sharing WAV files directly might annoy your friends when they receive a 150 megabyte email attachment. Compress WAV files using audio software. Audacity is a great place to start – it’s free, open source, and well supported.
Compressing a WAV file with Audacity is easy:
- Open the WAV file in Audacity.
- From the menu, File > Export > Export as MP3
- Name your file and save – default settings are fine.
DAW
DAW is short for Digital Audio Workstation, most commonly a software program used to record and edit audio.
Audacity can work in a pinch. More sophisticated programs are more expensive and have a learning curve but are worthwhile for more serious recording.
On Apple computers, GarageBand has a shallow learning curve and a direct upgrade path to Logic Pro for those who outgrow its significant (but still limited) capabilities.
Many audio interfaces bundle intro (limited but reasonably powerful) versions of DAW software such as Ableton Live Lite or Pro Tools First.
Audio interface
An external audio interface allows you to receive audio from multiple sources – for example, line-outs from a digital piano or microphones positioned around an acoustic piano.
If you’re recording a digital piano via USB, you may not need one.
Recording a digital piano
Depending on your gear, several methods may be available for recording a digital piano.
- Record directly from the piano to a USB flash drive
- Record audio from the piano via USB
- Record audio from the piano via line outputs

Quick-and-dirty flash drive recording
Recording directly to a USB flash drive offers the least flexibility but it also requires the least amount of gear. If you don’t want to fuss with a computer or don’t want to buy new gear, it’s a decent way to proceed.
You’ll need:
- A digital piano that supports recording audio to a flash drive
- The piano’s user manual
- A USB flash drive
- A computer
Do the following:
- Plug a flash drive into the digital piano’s host USB port and follow the instructions in your user manual.
- Once you’re done recording, remove the flash drive from your piano, insert it into your computer, and listen to the file to make sure it’s good.
- If you’ve recorded a WAV file, compress it as described in Types of audio files, above.
- Then share it with as big of a world as you’d like.
Record audio via USB
A select few digital pianos can act as digital audio interfaces, meaning that they output audio over USB when connected to a computer. This feature is incredibly convenient but unfortunately isn’t very common. In the list above, only the Roland RD-2000 and Yamaha CP88 stage pianos, as well as the Yamaha P-125 portable piano support it.
You’ll need:
- A digital piano that supports USB audio
- A USB A-to-B cable
- A computer
- Audio recording software, e.g. Audacity to start
Do the following:
- Use the USB A-to-B cable to connect the piano to the computer.
- Open Audacity and select the piano as your input source.
- Press the microphone button to start monitoring – listening to the input but not recording it.
- Play a few keys and check that the audio meter is showing activity.
- Press record.
- Perform!
- Export the audio as MP3.
Record audio via line-outs, basic
If your computer has a stereo line input, all you’ll need to get started is an adapter cable allowing you to connect your piano’s line output to your computer’s line input.
If your computer has a built-in line input, it’ll likely be a 1/8” (3.5mm) stereo jack.
If your piano has a 1/8” stereo line output jack, you’ll need a standard 1/8” to 1/8” TRS cable. The Hosa CMM-110 Stereo Interconnect Cable is an inexpensive example.
If your piano has 1/4” Left and Right line output jacks, you’ll need a Y cable with a 1/8” TRS plug on one end and two 1/4” TS plugs on the other. The Hosa CMP-159 Stereo Breakout Cable is an inexpensive example.
You’ll need:
- A digital piano with line ouputs
- A computer with line inputs
- An adapter cable
- Audio recording software, e.g. Audacity to start
Do the following:
- Use the adapter cable to connect the piano to the computer.
- Open Audacity and select the computer’s built-in line input as your input source.
- Press the microphone button to start monitoring – listening to the input but not recording it.
- Play a few keys and check that the audio meter is showing activity. Adjust the input level until your very loudest playing doesn’t hit the maximum level.
- Press record.
- Perform!
- Export the audio as MP3.
Record audio via line-outs, better
Some computers don’t have line inputs. Even if yours does, it may not provide a very high quality signal or you may have to choose between connecting headphones and connecting your piano.
In these situations, you’ll want to buy an external audio interface with at least two channels. If you don’t know what to buy, get a Focusrite Scarlett 2i2 for $160 and be done with it. If you must, you can go cheaper with a Behringer U-Phoria UM2 for $50. If you’re on Windows, it’s nice that the Scarlett comes bundled with DAW software so you can move up from Audacity without spending more money. The Behringer does not.
These external audio interfaces receive line-level audio via 1/4” mono jacks. If your piano has 1/4” Left and Right line output jacks, you’ll need two standard 1/4” TS instrument cables. The Pro Co EGSS-10 is an inexpensive example.
You’ll need:
- A digital piano with line ouputs
- A computer
- An external audio interface
- Cables
- Audio recording software, e.g. Audacity to start
Do the following:
- Connect the computer, external interface, and piano.
- Open Audacity and select the external interface as your input source.
- Press the microphone button to start monitoring – listening to the input but not recording it.
- Play a few keys and check that the audio meter is showing activity. Adjust the input level until your very loudest playing doesn’t hit the maximum level. Be sure to adjust both left and right channels equally.
- Press record.
- Perform!
- Export the audio as MP3.
Recording an acoustic piano
Recording an acoustic piano is considerably more involved than recording a digital piano. Table stakes include buying an external audio interface, a pair of microphones, and one or more high quality microphone stands.
We’ll discuss stereo recording techniques.
WARNING: DO NOT SKIMP on microphone stands. I’ve had a cheap microphone stand fall over and go through the front of a guitar. Do you want to pay top dollar to have your piano fixed, the one that might have cost you tens of thousands of dollars to buy? Spend the money on good stands with wide, heavy bases and counterweighted booms and think of them as an insurance policy.
Recommended equipment
- External audio interface. You’ll need one with at least two microphone
preamps and 48 volt phantom power.
- Focusrite Scarlett 2i2 ($160)
- Microphones. Choose the pair of small diaphragm condensers that matches your
budget. Note that the $200 Røde M5s are fantastic.
- Røde M5 matched pair ($200)
- sE sE7 matched pair ($200)
- Røde NT5 matched pair ($430)
- If you want to spend more than $430 on a pair of microphones, consider if your space matches the quality of microphones you’d like to buy. The $200 Røde M5s are already accurate enough to faithfully capture the sound of your forced air heating and cooling, footsteps in adjacent rooms, and car horns outside. Consider paying for studio time instead.
- Microphone cables. Buy decent mic cables with Neutrik or Rean connectors. The cheap ones have crappy connectors that don’t seat well and you’ll have to buy yet more cables to replace them. All of these are fine:
- Small folding table. Get a folding snack table for next to the piano.
It’s a great place to put your computer and external audio interface.
- Bed Bath and Beyond has tons of choices, for example.
For grand pianos
For grand pianos we’ll be using a coincident stereo microphone placement, meaning that you’ll only need one mic stand.
- Mic stand that won’t fall over. Choose one of these or similar.
- On Stage SB96+ studio boom stand ($115)
- On Stage SB9600 tripod studio boom stand ($140)
- Stereo microphone mount. Choose one of these or similar.
- On Stage MY500 ($11)
- Rode Stereo Bar ($50)
For upright pianos
For upright pianos we’ll be using a spaced stereo microphone placement, meaning that you’ll need two mic stands but won’t need a stereo mount.
- Mic stands that won’t fall over. Buy two.
- 2x On Stage SB96+ studio boom stand ($115)
- 2x On Stage SB9600 tripod studio boom stand ($140)
Reading
- Shure’s Microphone Techniques for Recording is essential reading. Before you try any special mic placements, try the positions that it recommends.
- The Mic It! book ($35) is a good supplement and goes over principles and techniques in a lot more detail than Shure’s guide.
- Røde’s Stereo Microphone Techniques post is a nice supplement and includes videos of several stereo placements.
Recording a grand piano
We’ll be using a coincident X-Y stereo placement straight out of Shure’s guide – it’s grand piano placement 1.
Opening the lid is essential!
You’ll need:
- Your acoustic piano
- A computer
- All the equipment listed above
- Audio recording software, e.g. Audacity to start
Do the following:
- Open the piano’s lid all the way or remove it entirely.
- Set up your computer, external audio interface, mics, stereo bar, and boom stand.
- Turn on phantom power on your external audio interface. On the Scarlett 2i2, do this by pushing the phantom power button on the front of the interface.
- Use grand piano placement 1 from Shure’s Microphone Techniques for Recording (page 11) with a 135-degree X-Y coincident stereo placement (page 22). Make sure the mic pointing at the bass strings connects to channel 1 of your external audio interface and the mic pointing at the treble strings connects to channel 2.
- Open Audacity and select the external interface (channels 1 and 2) as your input source.
- Press the microphone button to start monitoring – listening to the input but not recording it.
- Play a few keys and check that the audio meter is showing activity. Adjust the input level until your very loudest playing doesn’t hit the maximum level. Be sure to adjust both left and right channels equally.
- Press record.
- Perform!
- Export the audio as MP3.
Recording an upright piano
We’ll be using a spaced stereo placement straight out of Shure’s guide – upright piano placements 1 and 2. It’s tough to avoid hammer attack with easy upright placements, especially if your piano is up against a wall.
Opening the lid is essential! Lots of people like putting all kinds of stuff on top of their uprights. That’s great, but clear it off for the purposes of recording.
You’ll need:
- Your acoustic piano
- A computer
- All the equipment listed above
- Audio recording software, e.g. Audacity to start
Do the following:
- Open the piano’s lid all the way or remove it entirely.
- Set up your computer, external audio interface, mics, stereo bar, and boom stand.
- Turn on phantom power on your external audio interface. On the Scarlett 2i2, do this by pushing the phantom power button on the front of the interface.
- Set one stand up to the left of the piano and the other to the right.
- Set up the left stand with upright piano placement 2 from Shure’s Microphone Techniques for Recording (page 12). Make sure to hook this mic up to channel 1 of your external audio interface.
- Set up the right stand with upright piano placement 1 from Shure’s Microphone Techniques for Recording (page 12). Make sure to hook this mic up to channel 2 of your external audio interface.
- Open Audacity and select the external interface (channels 1 and 2) as your input source.
- Press the microphone button to start monitoring – listening to the input but not recording it.
- Play a few keys and check that the audio meter is showing activity. Adjust the input level until your very loudest playing doesn’t hit the maximum level. Be sure to adjust both left and right channels equally.
- Press record.
- Perform!
- Export the audio as MP3.
Where do you go from here?
Some ideas to start.
- Post a track on Soundcloud for others to hear.
- Pick a DAW and learn how to use it.
- Get some headphones and record to a click track. Learn both parts of a piece for two pianos / four hands and overdub the parts.
- Record yourself playing études or exercises – even scales – and get them perfect. Listen for that thumb thud or that little space where you’re playing not-quite-legato and get rid of it.
- On a digital piano, record each part with a different piano sound.
- On an acoustic piano, try different mic placements and see which one you like the best. Once you find your favorite, tweak it and see if you can make it even better.
- Record different instruments or your voice.
