C Diatonic Note Layout
The holes are numbered 1-10, and the position of the hole number indicates the low note in each hole. The blow notes are shown in the hole chambers toward the front edge of the comb, and the draw notes are shown at the rear of the chambers. The notes in between the blow and draw notes in the chambers are the normal bent notes available in each hole. The notes shown outside the chambers are the overbends, consisting of overblows in holes 1-6 and overdraws in holes 7-10. Note that overbends are available in all holes, but only those that add unique notes have been shown.
The discontinuous line of hole numbers is shown to emphasize the point that the note relationships invert at hole 7. That is, on holes 1-6 the blow notes are lower than the draw notes--but on holes 7-10 the draw notes are lower than the blow notes.

Most players who advance beyond the beginner level play in 2nd position 80%-95% of the time. (Playing in 2nd position means the tonic note is the 2 draw, which is a 5th higher than the key of the harmonica.) So, to think in the generic key of C when playing in 2nd position, you use the key of F harmonica. Here is the note layout of a key of F harmonica.
F Diatonic Note Layout
Another nice thing to see explicitly, instead of digging it out of other
charts, is how to play the same note at different places on the harp. The
range of a 10 hole diatonic is 3 octaves, so I've divided the table into
Low, Mid, and Hi to correspond to these octaves.
