Goodness, I think it was dreadful Again, I did not see it as a discussion on theory per se but more as a general discussion as to whether it is necessary in the pursuit of guitar playing. Is there another way to learn. As for your confidence in my knowledge of the subject, well clearly I have very little knowledge of the subject. But if you have listened to any of the tracks I post in the Jams or the Challenges you will know I am quite fond of 2 and 3 part harmonies. I find it interesting that with all the talk of scales and modes and such (and you don't get any "likes" when you contradict that) no one has ever said, "well, if you don't know any theory, how do you do that"? Music theory to me, evolved secondarily to music. I don't think the 1st cavemen beating out a rhythm gave much thought to simple/compound time or waltz time. I don't think the 1st instrument was played any other way than, "hey that sounds nice". I believe the theory followed as a way to explain what was happening and if you are into that well, good for you, I applaud your pursuit of knowledge. For me however, I have never really got past that, "hey that sounds nice" stage. It sounds nice cuz it sounds nice. So, if you have that sort of mind that turns towards explaining sound then "cool", have fun, but I don't believe you become a great guitarist by applying mathematics (theory) to your playing.I believe you are much better served by applying your heart to it. Please David don't be put off by MY ideas. I love a good discussion.
