I think I got a better understanding of it all last night…
Basically, you've got your different modes (major, minor, mixolydian etc) - these all have a differing pattern of intervals ie t t s t t t s
You choose which mode you wanna use (these can help define the emotional content of the music - major happy, minor sad etc) - you can apply any mode to any key (using the right interval pattern) and that then gives you the scale (7/8 notes)
From the scale you can build your chord (major & minor), plus work out a chord progression
Next wanna learn more about melody, but I reckon I understand the absolute basics now, which is a big improvement
So yeh thanks for all your help, and I hope someone else can get some useful stuff from this (assuming that it's right, of course!)
but after all that, yep if it sounds good... :lol:
