C Chords, Blues Guitar
62 qualities on C. The seventh chords are where a blues usually sits; the rest are here for the song that wants one.
Every quality this site draws on the root C, in 10 families. A blues leans hardest on the dominant seventh and its ninth and thirteenth relatives — a chord that would sound unfinished in a pop song is the resting chord here — and the others are for the tune that asks for one.
The guitar carries the rhythm under each sung line and the answering phrase in the gap the singer leaves after it. The grip below is what the rhythm hand keeps hold of through the bar, and the answering phrase usually starts from the same hand position, so the shape doubles as a map of where the next lick begins.
