Where is somewhere I can find a bunch of blues chords in tab format? The more the better. Thanks.
Blues? Yes please.
Rock? Yes sir.
Music? Give me a guitar and I'll play.
Study the music you're interested in and look at the chords. Generally Blues and Jazz favor extended chords: 7th's, 9th's, 11th's and 13ths... sometimes with altered notes. As a start, i would learn 7th (dominant, major and minor) and 9th chords all over the neck, since they tend to be always present in blues.
