GG, I guess that padymac's and my ideas of "dancing in the head" may (or may not) be different.When I am playing the folk dance music, I often have a "mental picture" of dancers that I am playing for and timing wise, I am concentrating on keeping the rythym right for them... Sounds (and probably is) crazy but it seems to work for me and timing is one area in music that I rarely have any problems with - it is accuracy of notes and the inability (some of the time) to move my hands quickly enough to get some of the triplets (I just don't go for them - it depends on my "form" in the session - I keep time but only play the notes that I feel capable of getting in) that I would like to be playing that lets me down.
