Would a 24 hole (diatonic/tremolo) harmonica not be better than a 10 hole one as there is a wider range of notes (I use inexpensive ones in the keys of C, D and A)? I would love to get one of these in the key of G (using the same tuning mechanism, which I think may be known as Eastern or Asian tuning) or other keys as well but these either seem to be very expensive or not available in the UK. Or else you contact shops etc which sell harmonicas but they never seem to get back to you, even via E-mail.
