The Dead seem to be masters of non-standard timing, ie. not 2/4, 3/4, or 4/4 timing. I was born and raised on 4/4 blues so these timings are very difficult for me to feel relaxed while jamming to them. Counting to 7 or 9 while sustaining a note just feels wierd. Any sugestions?
For me, it's about the grove.
I "feel" seven as

1 + 2 + 3 + 4 + 5 + 6 + 7 +
For eleven it's just like they accent it in the song

123 123 123 12
And if I can feel that groove, or pulse in me i'm right. To me, feeling odd time signatures came most easily when I internalised my time and "felt it" not played it.
