I am a former rhythm player switched to bass a few years ago. I really enjoy it and play in a trio with 2 other guitar players. (no drummer). Both guitar players sing, one of which is really good. We do older type stuff (soft rock, Sinatra tunes etc) and play steadily in a restaurant that has a busy bar trade after the dinner hour on Sat nites. I have a decent voice and have been asked to sing on numerous ocassions. My problem is I have a great deal of difficulty playing a bass line stedily and rhythmically and singing at the same time. Any tips on how to "split" my thinking so that I can sing or at least do some background vocals while not afffecting my bass playing? Thanks for the tips!
