You have to learn everything in order to be a complete musician. * Learning to read notes is important (you have to learn to read ahead, and interpolate, and recover). * Learning to play from chords is important (remembering that the chords are B E A /). * Learning to play from song structure is important (understanding that the chords are II IV V /). * Memorizing chord structure and song structure is important. * Learning to hear that the guitarist just decided to do an extra chorus in his solo is important. * Learning to hear that you just knocked your E string and it's gone flat is important. * Learning to pack everything you need for the gig is important. But most important is finding a teacher that inspires and motivates you and works with your style.
