Thanks for the great response folks!
Malcolm, I'll definetly check-out the Swedish Fiddle Tunes, and you're right , working out the harmony is an excellent exercise, but one I haven't quite mastered yet. I'm still developing an ear I guess.
winniemih and alison, thankyou too, great suggestions.
Barry T, as in TAYLOR? I have been visiting your site forever!!! Incredible site, and a perfect suggestion as I have Cakewalk so I'll dive right in and start separating the lead and harmony tracks now. Perhaps I'll get the "feel" for coming up with harmonies to tunes that way. Oh, thanks to Sorcha also, I've attempted the "thirds" before and it never sounded quite right to me, I'll work on it:) Thankyou all, Nancy
