Hi Hedy, and thanks for answering. Does your use of the phrase "current membership" mean that you're new to Mudcat? If so, welcome, and I like your writing style.

I'm familiar with the I IV V progression of short-lived chords within a song or tune. Does it also apply to the sequence of tunes within a medley? I mean, would you play a G major reel on the fiddle (with your guitarist playing G, C, D, Em) then go straight into a C major reel (with the guitarist playing C, F, G, Am) then a D major reel then another G major reel?

I remember from another thread someone said it was cool to shift from some G tunes into A tunes. This I to II sequence isn't something you see often in guitar chords for individual songs.

I wonder if there's any connection between how the chords of bars within a tune go together and how the keys of tunes within a medley go together.

thanks, Marion
