The single most benefical thing you can do to improve nearly all aspects of your playing is to listen
internally. Imagine the sound you'd like get out of your intrument. Take time hear what your going to play before you play it. The stonger the sound image in your head the greater the chance of you sounding the way you want. In the words of motivational speakers "if you don't know where your going you may wind up some place else. Make sure you listen to great players. You need to know the sound you want.
