Hi again...
Hi Dan... thanks for the comeback... much appreciated!

I'm really not an accomplished enough musician to actually know what notes make up a C7th. But I do know that when I play one on my guitar it always sounds the same and it doesn't sound "off or sour" to me every once in a while. Same thing when I play one on the piano. It always sounds the same, no matter how many times I play it. This is not whats happening with the song in question. For the most part, the C7ths and G7ths sound as how my ear is used to them sounding if I play them on a guitar or piano. But there are a couple of them in the song I'm doing that DON'T sound that way. I guess you could say that when I use these chords in my BIAB song they're not always consistent.

My song is a country style.
The style is: _POPPNOS.STY. Pop Piano 12/8 Ballad

I could send you the song - if I knew where to send it. It would be great to have you actually hear what I'm talking about.

Thanks again guys!!!
