Thanks Jonathan, but I am speaking live vocal performance over a style accomp.. I want more involvement than a Karaoke rendition. I envision singing melody with left hand piano and right hand stabs, arps, or something. I would then play second verse as instrumental as usual, then come back in with my vocal at the bridge. This is only one example, depending on the song.

I am only trying to get used to playing and singing at the same time, and since I would start with very familiar songs, I guess the right hand use while singing is the first question.

Thanks for your response, Jonathon, as you are well versed in this, to be sure.
