Using lilypond for feedback on practice

[Lee]

Hi

I'm wondering if I can use lilypond with wrapper app/Frescobaldi for giving
visual feedback on realtime playing of single notes - for timing and
pitch.   I'm researching this myself.

Before I dive too deeply in this.  Has this been done/tried?  I'm sketched
out a rough plan.

1. Can I extract the time in seconds and pitch/note/fret from the lily
score and how could I bind that to python.

Essentially I need match instrument input to score in real time.   But for
the moment this python binding is enough.


  \version "2.24.4"

  pentatonic = \relative c
  {

    a\6 c\6 d\5 e\5

  }

  \score
  {
    \new StaffGroup
    <<
      \context Staff
      {
        \clef "G_8"
        \pentatonic
      }
      \context TabStaff
      {

        \pentatonic
      }
    >>
  }
