Abstract: Harmonicas with the blow reeds forming a repeating pentatonic scale and the draw reeds forming a repeating pentatonic scale to facilitate ease of playability and musicality when playing pentatonic scales.

Abstract: Abstract: Harmonicas providing more notes and increased playability and musicality when playing blues scales. Disclosed harmonicas also provide functional minor scales.

Abstract: A harmonica with a repeating major scale configured across the draw reeds and a repeating major scale a half step lower than the draw reeds configured across the blow reeds. This configuration produces a chromatic instrument where all the notes of a major scale can be bent down to the next lower scale tone for musicality. The linear scale configuration provides trill and glissando sections for ease of playability and musicality.

This configuration produces a chromatic instrument where all the notes of a major pentatonic scale can be bent down to the next lower scale tone for musicality. It provides more notes and more bends when playing pentatonic scales and the repeating pattern facilitates easy learning.
