I am beginning to question if I need to, necessarily, always play organ, strings, piano, etc on the left. It is probably a carryover from organ.

If the arrangement has full comp, I could do without it sometimes, but I am use to creating movement on my left hand during sustained parts.

The reason I ask is that my Yamaha has left sounds depending on the style. Many times there is none, at least out of the box(MFD). Also, I see many pro videos with the left hand not being glued down and freeing it for port/mod wheels, changes, etc.

I would appreciate a consensus, if indeed, there is one.
