If a note is worth playing then its worth playing clean. I like to tell people starting out don’t worry about speed, that will come, learn to play clean with good timing. Timing is everything! When I’m playing with the Atkinson Family I ask myself what can I do to make the person singing lead or playing a cut sound better. Sometimes the answer is nothing. Learning when to not play and learning not to walk on whoever is being featured at the moment is very important. It seems some players never learn this.
