This is the most common type of harmonica. With ten holes that offer 19 notes (two notes each (blow and draw) with one repeated (2-draw and 3-blow are both the same)) within a three octave range, the diatonic harmonica is designed to allow a player to play melody and chords in only one key — the most popular being the keys of C and G. Here is a standard diatonic harmonica's layout in the key of C:
Although there are three octaves between 1 and 10 blow, there is only one full major scale — between holes four and seven. The lower holes are designed around the tonic (C major) and dominant (G major) chords. The tonic triad (C-E-G) is given the blow, and the secondary notes (D-B-F-A) the draw. *
