I started this discussion on that intangible difference in swing feel between gypsy and american jazz players a while back but had a new observation from a recording I'm doing.
Of course a lot of it is just accents of course, but it felt like there was something else as well besides just the la pompe accents.
I noticed while editing a recording with my group (which is me plus a lot of jazz players) that I consistently was placing beat 3 a little earlier than the rest of the group. Could be just me or could just be I was having a messed up day, but listening really carefully to the effect it had I feel that might be a big thing in the difference between the American swing and the Gypsy swing.
Is there something too that or was I just playing poorly that day?
