Watch the Developing a Sound online guitar lesson by Bruce Arnold from Guitar Physiology Survival Guide

Developing a sound that allows you to relax and work on technique in a musical way will make a huge difference in your progress. If you use an electric guitar make sure your guitar is properly set up and your amp gives you a tone that allows you to hear the type of sound you want. This will give your ear encouragement, giving you the sound environment you need in order to improve.
