Vixen,

It is very difficult to help you with rhythm in this forum...I could show you some things that I do, but to describe them is quite difficult. You're right, you want to get into a groove...and Jerry is absolutely right in that the best way to keep rhythm (or to avoid risking losing it) is to somehow keep it physical. With regard to when to start singing, I think it is less about rhythm and more about reaching agreement ahead of time on either counting in, or some subtle "clue" or "hint" (when I nod my head, or just after this chord).

NOMAD looks like a great event that I will have to miss...
