Hi,
I'm new here. Earlier today, I was practicing the piano and happened to be playing an arrangement of Blueberry Hill from the Reader's Digest book, Remembering the '50s. In the bridge, there is a C7 B7 chord sequence. It didn't fit any progression I was familiar with, but it sounded great. So I did a search for "music theory forums". I don't recall the exact search text. This forum did not pop up, but another one in the Banjo Hangout website did. So I posted my question over there. I got several helpful responses.
One respondent asked why I was posting on a banjo forum and I replied that it was because that was what came up in my search. So then I did another search and that time this one came up. As I was browsing, I happened to see this thread, which I thought was an incredible coincidence.
Anyway, thanks for the discussion. I don't understand everything you are saying, but it gives me some things to read.
I scanned the 4 lines of the bridge and attached it as a jpg over on Banjo Hangout. I tried to attach it here as well, but that doesn't seem to be working. Preview doesn't seem to be working for me either.
