I've sang in choir for 50 years, played Trombone in high school, and am a Church Choir Director. I can read music (both clefs).
I mostly play hymns on keyboard/organ. I can play both right hand parts, and both left hand parts, but I can't play all four parts together.
I want to be able to play both notes with right hand and a chord with my left. I cannot read both staffs at the same time and want to know which note in either clef I can base my chord on. How can I determine which chord to play?
