Six-Sided Harmonica
Harmonica is not unfamiliar for everyone. I believe everyone ever played it before. The picture above is the six-sided harmonica that is made by the renowned Hohner instrument company founded in Germany in 1857.
combines six harmonicas into a single component, creating the largest tonal range available in any Hohner tremolo model. Tremolo harmonicas employ two reeds per note, and each harmonica on this instrument has 24 double holes for a total of 48 reeds per harmonica that produce a warm vibrato characteristic of the world-famous Hohner sound.
