The tricky passages

  • Bar 6: fast runs (4.0 notes per second), a melodic leap (more than an octave (15 semitones)), notes outside the key, lots of notes
  • Bar 10: fast runs (4.0 notes per second), a melodic leap (minor seventh), notes outside the key, lots of notes
  • Bar 32: fast runs (4.0 notes per second), a melodic leap (minor seventh), notes outside the key, lots of notes

The plan: 27 days

Half an hour a day. First I help you understand the map of the piece, then we lay down the chord framework, learn each section phrase by phrase, work on the tricky passages, put it together and bring it up to tempo, until you can play it from memory.
