What's up guys. Can anyone tell me where to find the chord formulas for extended and altered chords? I want to learn how to construct chords like b9's, 11's, 13's etc. I want to add some of those Hendrix type chords to the repetoire. I looked all over the usual lessons sites, but nobody has the formulas that shows how to build them. ex. (1, 3, 5, b7) Thanks!
