Hi. I've been playing properly, I.e. hour plus a day, for about 18 months after always having a guitar for years but only playing open chords and the same few songs. I've got much better since taking it seriously. My finger strength and dexterity have improved immeasurably. My question is this. How seriously do I need to take learning theory ? I know my chromatic scale and my am pent and major scales. I know how maj, min, sus and 7th chords are formed. But I have no intention of performing or writing or teaching....I just love learning songs. I can see how some theory along with interval and ear training can help with transcribing songs. That's probably all I'd use it for. My technique I tend to practice by learning songs with those techniques in...I.e. finger picking, hybrid picking, palm muting etc, as I feel it focuses my mind more than exercises do. I do enjoy learning some theory once I give in and pick up a book or look online. I just feel like I should learn it rather than wanting to.
