Q: What is a chromatic harmonica?
A: Extending the discussion of general types in part 1, a chromatic harmonica is a harmonica that has all 12 notes in an octave directly available. It is actually tuned in a diatonic scale, but it can be raised a half step by pushing a button on the side -- BB
Also from "Post #2 General Stuff" 2 Nov 1992 JE:
The standard chromatic tuning is different and called "solo" tuning. The entire scale is repeated in each set of four holes (just like holes 4-7 of a diatonic). 12 hole chromatics are available in 12 keys. 16 holers are only available in C. A 16 hole chromatic has four complete C scales, with the C repeated in every octave. See layout below...

Notes: 1. The cover plate numbers on different models/brands of 16 hole harmonica will differ. Some show the first four holes with a dot beside them to indicate the octave below middle "C". Middle "C" is found in hole 5 (the 5th
hole) on a 16 hole chromatic.
2. Hole 16 tuning (slide in) is slightly different from it's lower octave companions (1., 5, 9, & 13). Hole 16 contains a "D" note where you might expect a D# (Eb). Why? I don't know. (hope these drawings got through the mail OK.) -- "Post #2 General Stuff" 2 Nov 1992 JE
