A number of years ago I learned to play the chromatic harmonica a little (6 or 7 melodies). I stopped playing and the other day decided to try again. I just got this 10 hole chromatic harmonica (made by a subsidiary of Hohner). It is in the Key of C, but can play all keys and has a range of 2.5 octaves. Wish me luck.:)
By the way, chromatic harmonicas normally have valves (windsavers) which can stick and often did when I was playing. This design does not have valves.
