One other thing I do in sessions when I am trying to learn a tune is hang out on the fringe with a whistle in the appropriate key, and start sticking in the octave notes as they come round, and then some of the inbetween ones, leaving the runs till last. I find I can sometimes learn a whole tune this way in a session (and then be totally unable to reproduce it alone).[grin]
Playing this way kicks my intuition into high gear, and sometimes I am amazed by what my hands know if I'm not thinking about it.
Blessings,
