Piano Roll
Use Piano Roll to watch notes flow across the screen like a modern player piano roll. Scrub back and forth, change the sound, and connect what you hear with the moving note patterns.
See Notes Over Time
Each note appears as a visual event. Higher notes sit higher, lower notes sit lower, and longer notes take up more space, making the music easier to follow as it moves.
Scrub Through the Music
Move back and forth through the piece to inspect a passage again, slow down your listening, and notice how repeated shapes match repeated sounds.
Piano Roll Practice Ideas
Follow the Melody
Track the highest or most active notes to understand the shape of a musical line.
Notice Repetition
Look for repeated note shapes and listen for how they create familiarity.
Compare Note Length
Longer notes can feel sustained, while shorter notes can create motion and rhythm.
Change the Sound
Try different sounds and listen for how the same note pattern can feel different with a new tone.
Inspired by Player Pianos
A traditional piano roll used paper with holes to play a self-playing piano. This online version keeps that idea visual, so you can watch the music pass by as notes trigger sound.
Follow Familiar Melodies
The scrolling view helps you notice entrances, pauses, repeated phrases, and changes in density while listening to well-known piano pieces in a visual format.
