I've only been playing guitar for for about 16 months. I work out of five or six instruction books for self learners. I had never before played any musical instrument nor had I ever had voice or music theory music lessons. I'm learning to sight read music but play mostly tabs because I still can't read music fast enough to play without tabs.. I'm beginning to see references to scales in some of my instruction books and how important it is to learn and practice the most common scales each practice period. I usually practice one to one and a half hours five days per week.
Let's hear some input on the importance of learning the most common scales and practicing them on a regular basis.
