Perfect for traditional harmonica bands, groups, and trios. The most versatile chord accompaniment harmonica ever made, Hohner's 23-inch 48 Chord is actually two harmonicas hinged together. The player has access to 48 chords. The top section plays major chords on blow and 7th chords on draw, while the lower unit plays minor chords on blow and alternate draw chords between augmented and diminished. This model also uses windsaving valves to maximize airflow to its 384 reeds!
