Harmonica with a blues scale based on the minor pentatonic scale, which is formed from the pentatonic scale in the minor key by adding the diminished fifth, comprising at least 10 combs, which are tuned to an arrangement of notes of the blues scale with a multi-octave range, and the comb assignment of the blow and draw channels is determined by a sound arrangement of the scale-specific notes of the minor blues scale, for which purpose the three adjacent combs of at least one octave are tuned to the blow notes (1), (4), (5) and to the draw notes (3.sup.b), (5.sup.b), (7.sup.b).

A harmonica including at least: a comb having a plurality of chambers; a first plate having a plurality of blow reeds; a second plate having a plurality of draw reeds. Wherein each chamber of the plurality of chambers has at least one material projection, each material projection being configured to reduce the oscillatory space of a draw reed; and in that the harmonica has at least one additional plate arranged above the first plate and has a plurality of additional material projections, each additional material projection of the plurality of additional material projections being configured to reduce the oscillatory space of a blow reed.
