well then, you might say Irish music is more diatonic than not.
Well, I have yet to hear of an Irish tune that's unarguably built on a non-diatonic 7-note scale. But there are hundreds of tunes in other cultures that ARE unarguably built on non-diatonic 7-note scales. You don't need any "ignoring" to make that conclusion.
I don't mean to be a bully, but geez, obviously there was a bit of a misunderstanding that has been somewhat cleared up, but I don't see anyone giving an inch.
Talasiga: Gapped scales are non-diatonic, and have their own flavor, and are prevalent in Irish music. Even if you weren't referring to them, surely you can see this point. And, some western (non-Irish) music does use non-diatonic 7-note scales.
Bloomfield: Irish music is not built on non-diatonic seven-note scales in the way that Klezmer, Arabic, etc., music is -- while a few examples of accidentals and chromaticity can be found, I doubt you can find any traditional tunes built solely on a 7-note non-diatonic scale, as you can in many other traditions.
This is just a very simple, basic difference between music from different traditions. It isn't dry, nit-picking theorizing. Knowing the scales prevalent in a tradition certainly helps you pick up new tunes. If nothing else, it lets you know that you can play most Irish music with a six-hole diatonic whistle. Isn't that nice to know?
I guess some buttons are being pushed here, because the reactions I see don't seem to match the concepts being presented, from either "side."
