nah....that's it....i never play with a band or a singer..always play as a solois..so it become a habit to play melody in right hand and chord in my left hand....i wanna play in a band or acompany by a singer..so if u play in a jazz band u only play with ur right hand??
now i read a jazz piano book...cos i think a jazz pianist is a perfect example of a good piano arrangement..they have a good feeling when improvise a song...and they usually don't use any kind of sheet...
