You may not be disagreeing as much as you think. What you put in bold is just what I was saying when I made that comment about experienced traditional musicians who have already learned hundreds of tunes by ear. The trouble, is if you "learn a tune" from dots you are not organically incorporating all those nuances that I referred to - as you learn. You have to try to add them in later. It can work as long as you are very experienced already. Not only that, there are so many different "versions" in the tune books (I gave all mine away years ago) that you end up with dot-learners arguing about which version is "best" or the "correct one," or telling someone else that they're playing it wrong. A dead giveaway, is that. Many an enthusiastic youngster is so impatient that they try to pick up dozens of tunes from the dots as quickly as possible in order to be able to join in in sessions. In most cases I've seen, their enthusiasm rapidly drops off. In m'humble you can't beat the real traditional way of learning tunes, which is by listening to real traditional musicians playing... It's slow, but it works.
