EarPlay · Practice. Create. Refine.
Your music.
Your way in.
Bring your music, build your ear, and develop your next arrangement. Practice in EarPlay, create instrumental parts with EarVolution, and listen closer with a whole-song error heat map.

A LITTLE PRACTICE, EVERY DAY.Illustration
From listening to playing.At your own pace.
Start with a song you care about. Your personal collection is the starting point.
Music first. Practice follows.Inside Earplay
Make listening an active thing.
A browser-based workspace for exploring music and practicing along with it.
Listen, then join in.
Open a ready song, start playback, and allow microphone access when you want to capture your playing. Explore the pitch display, recordings, and practice feedback.
Make the reference useful.
Use prepared lyric and pitch references where available. For your own imports, add and align lyrics in the editor, then return to the phrases you want to learn.
A work in progress, with clear limits. Visualizations and automatic transcriptions are estimates. Use them alongside careful listening.
On your phone: open the app in your browser and try a short session first. Microphone, playback, and timing behavior depend on the phone and audio setup. Keep Earplay visible during practice; mobile compatibility is still being tested.
EarVolution · Inside EarPlay Studio
Let the next part evolve.
Your recording is the starting point. Explore new instrumental ideas, keep your own judgment, and build an arrangement one part at a time or evolve an ensemble together.
Start with your sound.
Record or import your music in the Ubuntu desktop Studio. Work with the full recording or separated stems to give your arrangement more remix flexibility.
Evolve, audition, keep.
EarVolution proposes instrumental parts and searches notes, phrases and instrument choices. Evolve a single part or a defined ensemble. Control busyness, variation, smoothness and repetition; compare candidates and accept the ones you want. Keep accepted tracks as you add another part.
Explore the balance.
Auto mix searches track levels, then lets you compare the original and proposed balance before applying it. The DT model’s prediction error guides these searches. Your listening decides what sounds right.
EarVolution is a desktop Studio feature and needs the configured model runtime. The browser player is available separately.
Planned · Classroom composition
Student ideas.
A band’s own music.
We’re planning a teacher-guided workspace where students arrange a song they want to play or create something of their own. They bring musical ideas, shape their parts and build the arrangement together.
Planned, not yet available. This classroom workflow is on Earplay’s development roadmap.
Start with student ideas.
Students would play, sing or enter a melody or rhythm, then listen to possible arrangements. They would choose parts, edit notes and phrases, and decide which ideas to develop.
Keep the phrases that matter.
The planned workflow would let students lock a favorite phrase or a whole part, then evolve the remaining parts around it. Each candidate would be scored in the complete ensemble, including the music the class chose to keep. Listening and student choices would guide the result.
Write for the band in the room.
The teacher would define the actual instrument roster and each part’s playing level, pitch range, rhythmic difficulty and breathing needs. The teacher would review and approve the arrangement before the class rehearses it.
Bring the arrangement to rehearsal.
Planned outputs include printable parts transposed for each instrument, MusicXML, MIDI and practice audio, so students could rehearse and revise the music they helped create.
First, one shared classroom computer. The initial plan is for the teacher and students to work together on a shared screen. Optional student devices could follow later; they would not be required for the first classroom version.
New · Experimental song review
Find the moments
worth another listen.
A whole-song DT error heat map highlights places where the recording differs from the model’s musical forecast.
Scan the whole recording.
Choose a song from your EarPlay library or upload an audio file. See prediction error over time and across frequency bands, with quiet and unscored regions shown separately. Recordings up to 30 minutes are analyzed in full.
Listen to the hot spots.
Adjust sensitivity, review the strongest passages, or click directly on the map. Play each passage with a little surrounding context and loop it to decide whether it needs work.
Possible mistakes, not automatic judgments. An unusual chord, a new instrument or a deliberate break can also create high prediction error. This is an experimental listening aid; it cannot prove a wrong note or grade musical quality.
Sign in to EarPlay. Uploaded audio and reviews stay in your account; the original recording is unchanged.
Instructional videos
See it. Hear it. Try it.
Two short walkthroughs to help you find your way into practice, on your own or with the band.
First steps with Earplay
Listen closely, explore the parts, and find your own way into practice.
Circle & Strip: Play together
Follow the band’s parts and learn the view, zoom, playback, mixer, and setlist controls.
Instrument lights · In development
A nudge toward
the next note.
We’re exploring lights on or near your instrument: a flash for an upcoming note, with adjustable advance time and brightness. The goal is to offer guidance that fades as your ear and confidence grow.
Future cue concept
Phone playback + a connected light controller.
The GaiaTonic connection service supports device pairing and scheduled cues. Timed instrument parts and physical controller testing are still needed before lights are ready for practice.
