    A few minutes a day with this training exercise will greatly improve your piano music sight reading skills. It is adjustable to any skill level via preset levels or custom settings including key signature, note selection, accidentals, practice range, labels, and ledger lines. Optional piano sounds also make this a great ear training drill. A graph shows your progress during a session. This site should be in every piano teacher and student's favorites.
