                                 ABSTRACT
Harmonics  are  disclosed  in  which  the  pitches  of  the  draw-reeds and
blow-reeds  are  arranged  such  that, in each of at least seven successive
cavities,  the pitch of the blow-reed is equal to or lower than that of the
draw-reed.  Disclosed  harmonicas  also  feature  reeds  of  three  or four
adjacent  cavities  arranged  to enable them to produce all twelve notes of
the chromatic scale, or provide reed arrangements in which a major or minor
chord  of the draw key-note is repeated by draw-reeds in successive sets of
cavities,  and in which at least four adjacent cavities produce an extended
chord  of the blow key-note. In many disclosed harmonicas, the blow-reed in
each cavity is lower in pitch than the draw-reed.
