Hi Guys here is my perspective. when I started out,I'm natural righty I played to my right conga-tumba. when I started to play
3 congas I played all
3 to my right, but felt unbalanced. So I took the conga to my left
quinto in middle and tumba to my right. When I play 4 congas its
3 across and one in front middle but i kinda diamond shape it . When I play 5 congas its
3 across 2 in front and the set up for me is Left-conga-middle
quinto-right-tumba then in front of the
3 I use 2 congas and tune them accordingly to my ears and sound. I have seen guys play 4 to there right Like Patato-Jerry Gonzales,etc. I"ve seen crazy Ritchie Flores try and play 7 with in a V shape with
3 on each side and one in the middle, but that is overkill, for me and doesn't really work,especially with Latin music. And I have heard,there is a blind drummer in Africa that plays up to 10 drums. So have fun and experiment with positioning and sounds....try it you'll like it!
