rach3 turns piano practice into a conversation

rach3.com Visit website

Editorial interest 82/100 Selection signal · not a rating of the site

An open-source piano practice app that turns requested pieces or supplied music files into lessons, then offers feedback on what to practice next.

Landing page captured for the 2026-11-11 issue.

For: Pianists practicing with MIDI, scores, or video
Worth noticing: Customization changes are saved as versions on separate branches, and the original interface stays locked so users can return to it.

Field notes

For a requested piece, the app says it searches for free MIDI, sheet music, and YouTube options, then lets the player listen or look before selecting one. It also accepts existing MIDI, PDF, video, or YouTube material; the site notes that audio transcription and PDF recognition are experimental. Interface edits are saved as separate versions, while the original version remains available to restore.
