Ooh, Celtic Harp. I don't play, but sounds fun hehe. So I'm assuming its similar to the irish lever harp? Bet it's a nice instrument, but I'd think it'd be tricky to write for since you have to be careful with sharps/flats due to how the harp is tuned and played. Had an acquaintance mention that while playing, on any given note, you could only go sharp or flat, but not in the other direction. (hence, I've not actually written specifically for that instrument.....yet...*cough*) I'd assume modal sounding would work well though. Eh, anyways, I'll end the gush/rant by saying celtic and gaelic music/instruments are probably one of my favorite genres in music. ^_^
Oh, and to add, since I totally forgot to put include this, I did sing in college choir for a year or two before things got busy. I'm a baritone or 2nd bass, whatever you wanna call it.
