Piano technique

Let's make piano exercises e.g. scales and arpeggios more fun!

todo

  • Convert this list into a project plan.
  • Design diagrams.
  • Minimal API example: /hello returns "Hello World"
    • API endpoint in server.
    • Connect via Router in Express.
    • Client side just display plaintext.
  • Two phases (expanded below):
    1. MIDI input (easier, but limited to digital pianos)
    2. Raw audio input (extra step: convert to note on/off timings)
  • Convert time from absolute to elapsed, with first note on defining t=0.
  • Generate exercises starting with C major scale.
  • Given an exercise and a performance of it, assign a score accounting for:
    • Tempo consistency.
    • Volume consistency (from note velocity).
    • Missing notes.
    • Extra notes.
  • Track progress:
    • Scores over time, grouped by exercise.
    • Database? Cache? User accounts?
    • Pick up where you left off.
  • Choose useful libraries e.g. for MIDI, FFT.

todo: MIDI

  • Extend Web MIDI examples.
  • Pair note off events with note on events, determine time on.
  • Piano emulator to test without hardware available? (Just emit MIDI messages.)

todo: raw audio

  • Convert raw audio to note on/off timings.
  • Piano emulator to test without hardware available?
