I think this could be a fun and interesting thread : )

I have been focused on my pop songs - and practicing more often, and I do see progress. Thanks to all that have contributed to my posts about hearing changes.

That said - as I analyze tunes, I sometimes run across changes that go outside the key temporarily to add interest, and that don't neatly fit into the 'theory'....granted, you can explain anything away if you are determined to. My guess is that they are often just temporary modulations that fit well with the melody to add interest in our ear by going out of what we typically expect just a little.

Are there any songs (popular that other people have heard would be best, if you can) that stumped you in terms of analysis, until you finally made some sort of reasonable theoretical connection, or that for which you never really found a good explanation ? Perhaps your sharing will lead to others giving some theoretical relationship.

I'll start off with one:

Peter Framptom - Baby I love your way, Verse 1

G... Bm7/F#... Em... Em..(D)..C...C...F9....

Clearly the key of G - but what's the deal with that F9 ???
