Patent ID: 8153875

Claim:
A harmonica including a body providing a series of adjacent cavities and a plurality of reeds each of which is responsive to the passage of air normally to produce an audible musical note of a certain predetermined pitch, a pair of said reeds being associated with each of said cavities such that one of each pair of associated reeds is a blow-reed responsive to blowing into said cavity to produce a blow-note and the other of the pair of associated reeds is a draw-reed responsive to drawing on said cavity to produce a draw-note, said harmonica being characterized in that: (a) in any two adjacent ones of said adjacent cavities, the pitch between the reeds responsive to one of the said wind directions, is the interval of 1 & ½ whole steps, thus forming a series of four, repeating, four-note, diminished chords that function as dominant chords of the other of said wind direction's tonic chords, and, (b) in the adjacent cavities of the other of the said wind directions, the pitches between the reeds are a repeating series of intervals of 1 & ½ whole steps, 2 whole steps, 1 & ½ whole steps, and 1 whole step, thus fowling a series of two, repeating, four-note, extended, relative minor and relative major chords that function as tonic chords in relation to the dominant diminished chords of the opposite wind direction, with, (i) the relative minor chord's adjacent cavities being a stacking of intervals, rising in pitch, of 1 & ½ whole steps, 2 whole steps, 1 & ½ whole steps, and 1 whole step in a repeating manner, and, (ii) the relative major's chord's adjacent cavities being a stacking of intervals, rising in pitch, of 2 whole steps, 1 & ½ whole steps, 1 whole step, and 1 & ½ whole steps in a repeating manner, and, (iii) said relative minor and relative major chords being comprised of the same pitches, and, (c) the predetermined reed pitches, in each cavity, of the said wind direction that forms the tonic relative minor and major chords, are at least ½ step higher in pitch but not greater than 1 whole step above the predetermined reed pitches, in each cavity, of the other of the said wind directions that form the dominant diminished chords, and, (d) the first occurrence of the root note of the tonic relative minor or relative major chord's intervals that centers the invention's four-cavity repeating series can be located in either the first, second, third, or fourth cavity.
