please help me out here... What's a diatonic scale and how is it different from the traditional scale?
I thought that a diatonic scale was a major or a minor scale (I used to think of it as "not chromatic"), but Wikipedia http://en.wikipedia.org/wiki/Diatonic_scale
has proved me wrong (if you trust wikipedia that is). Apparently the set of diatonic scales includes also the church modes (Ionian, Aeolian, Dorian, Mixolydian, Lydian and I forget the rest).
So the "traditional" major and minor scales are a subset of the set of all diatonic scales... I think.
Yes I agree with that. Diatonic though is simply a way of describing something which contains ONLY the notes of the scale (whatever that might be) - i.e. no chromaticism.
Many instruments, largely folk, are diatonic (tuned to a specific scale). The melodeon (button accordion) I play is diatonic - it has two rows of buttons, one tuned to Gmaj and one to Dmaj. Mouthorgans and penny whistle are the same which is why they come in different keys. Bagpipes of various sorts are diatonic though often have extra keys grafted on for a bit of chromaticism.
