Chords - How to Figure Out Which Chord is Which?
So I get that chords are made of triads, and those triads can have extensions and different voicing's, but how do you figure out which chord is which? For example, if I were to play an E chord, would I build it off of a C major scale? or do I use a E major scale? And if it has some fancy voicing's, how would I know its an E chord?
