Clip from a show we played a few weeks back at Agenda.  That was a fun night!  As I have played more salsa, I started simplifying my note choices and getting into the groove more.  I think, especially in a setting like this for dancers, the groove is more important than complex harmony, but as you are able to groove better you can get more interesting note choices in there and keep grooving.

Of course what I wrote above is not a step by step guide. But simplifying what you play is an important piece. Really listening is another part of it. And for salsa, knowing how to dance can help.  A solo with one note can sound better than a much more harmonically  complicated solo, depending if the other dimensions of music are happening.
