Hope you realize this
Its a cool idea nad all since I used to play trumpet and sitll play a guitar ( and trumpet partially) I know the notes. Im not sure if it was on purpose but there isn't a note called H. the Musical scale usually starts on C for key of c (guitar and piano) and goes C, D, E, F, G, A, B, then back to C making it an octave ( 8 notes going from same note to the same note but a higher pitched version). Suggestion is to update it and add a piano in the preloader that can play the notes so people not musically inclined can learn generally the notes.
