I've been self-learning piano. I can play a song, like "Yesterday", from one of those E-Z play today books. What do you when a left hand chord seems to interfere with the right hand notes? I mean, they are physically getting the fingers crunched together and using the same keys at the same time. Do you drop the chord down an octave, thus moving the left hand away from the right hand? Do you use some inversion of the chord, so it drops the left hand down a bit (to the left) and out of the way? Or do you just let left and right hand fingers land on the same piano keys at the same time? In general, I never really know on what ocatave I should play a chord. And I don't know if I should play an inversion or a root. I just try to play whatever sounds best to me.
