An acoustic backing I've not done anything with yet.
I was trying to get the 7/8, 5/4, and 6/8 playing and changes to be better!
It is a nice structure and the dobro guitar sounds nice!
It is actually made up of tricks I use quite often;
1. Just two seventh chords in one section - check.
2. Descending chord progression for a section change (in this case from C to G/B, G/A, G) - check.
It's the fact of the time signature changes that I like so much, and it was purposely written that way!
