quote: Ten or twelve chords? somewhat over the top I would say.
I've heard that before from country western singers. They seem patriotic about the three chord maximum, as with pickup trucks and not speaking Spanish in school. I've never tried to tell them they should use more than three, but they often tell me I shouldn't. I guess I'd better not sing Schubert's Ave Maria around them. I just counted and it turns out I use 33 chords for that.
