Incorrect Harmonica Range
The range for "Harmonica" is incorrect with a caveat.
The upper range of ALL chromatic harmonicas in C is D7.
The lower range of 3 octave (12 hole) chromatic harmonicas in C is C4
The lower range of 4 octave (16 hole) chromatic harmonicas is C3
There is also a 3.5 octave (14 hole) harmonics with a lower range of G3
I don't know if this justifies the creation of three separate instruments, I'll leave that up to you.
