Like DonM, it's 99% left hand chords, melody in the right hand. I've recently started doing some vocals and when singing use right hand fills or a midi file depending on the tune. IF I'm using a 76 key arranger I'll sometimes just turn off all arranger functions and play piano solo. I play a number of styles of music including 40s, 50s, 60s, some 70s, broadway show tunes. Genre include jazz, blues and country.
