I've been playing the major scales from Kirks "Ultimate Stretching excercise" and I've learned them quite well. Now that I started to look around on youtube about major scales I found several videos about it and none of those major scales were the same as kirks lesson. Here's one of them:
YouTube - Mastering The Major Scale - Guitar Lesson
I'm very confused about all this. I thought there were 13 major scales and that all were included in kirks lesson but that is something similar but yet different from that lesson. Could someone explain to me firmly and simple as you can how it works? (Keep in mind that I've only been playing guitar for about 2-3 months and I knew nothing about guitar playing before then)
