hunh, my previous post is based on the idea that the chord in question was spelled C F G Bb.

while I was typing someone has posted that the chord in question is spelled Eb B C F. Some one else has interpreted this spelling as F7. errrrrr....

ahhhhhh, what the hell... I think I will just quietly withdraw from this conversation :)

To the original poster: if your chord is spelled C F G Bb, then see my post (also M.Ted had some useful stuff to say). ok, I have one more bit of advice -- you can't learn harmony from a website. Chords are not finger diagrams.

well...bye! have fun with it.
