Chromatic Harps

Chromatic harmonicas allow a built-in slider to cover all semitones of western music. Thus, all styles of music are open to you. In contrast to the chromatic harmonica, the diatonic harmonica only has reeds that produce the scale's own tones of the key in which the harmonica is tuned. A diatonic C major harmonica therefore only has the notes C, D, E, F, G, A and H.
