So ive been reading a lot on chords and scales. And I'm a bit confused on how to apply it all. For instance on a major chord. The suggested pattern is r-3-5 which is kind of restrictive. And it makes me think it makes no sense to learn the scales beacause no chords use M2, P4, and M6. But I hear a lot bassists useing more than r-3-5 when there guitarist is playing a major chord. During the line do you have to start on the root? When you switch to a different style chord Do you keep it simple? Beacause it sound weird to me to play a 3rd and switch to a flat 3rd for a minor.
