Lumikey is a music learning tool that transforms sheet music or YouTube videos into an interactive, falling-note experience on your keyboard. Watch notes descend and play them as they land, then use practice features like slow-motion playback, looping, and separate hand practice to master pieces at your own pace.
Paste a YouTube link or upload an audio file, and all processing happens locally on your Mac or PC — nothing is sent to external servers. Ideal for piano students and musicians of any level looking to learn by ear and sight-reading together.
