The trouble with saying that notated tunes are bare bones is that all the other aspects of playing a traditional tune, the ornamentation, the variations, the lift and the lilt ARE part of those "bare bones" and are not just add-ons. Good instincts require that they are all integrated into the "learning" process. To quote, or misquote, Alan Ng, that's how you get to "play it right." It's decades since I consulted a "tune book."
