Could you build this?
Partial The falling-notes engine, MIDI input, practice modes, and sheet-music view are all vibe-codeable in a browser using the Web MIDI API and canvas. The hard part is the 4,296-chart library, which needs licensed or carefully transcribed classical note data.
What it would actually take: Build a client-side web app using the Web MIDI API, a canvas or WebGL falling-notes renderer, and a timing engine that grades hits against audio-clock timestamps. Sheet music can come from a notation library such as VexFlow or a MusicXML renderer. The real barrier is the chart corpus: sourcing public-domain or licensed MusicXML/MIDI for thousands of pieces, aligning and fingering them, and quality-checking each one, which takes music-engraving knowledge and time.
