I've been studying the standard Have You Met Miss Jones and I came across a very interesting chord progression in the B section of the piece. The A section is pretty typical and the key it's in is F major, but once you hit the B section, there's 8 bars of pretty interesting chords.
B section chord progression:
Cm7 - F7 - BbM7 - Abm7 - Db7 - GbM7 - Em7 - A7 - DM7 - Abm7 - Db7 - GbM7 - Gm7 -C7 - FM7
Now obviously you can chunk out these chords into ii7 - V7 - I7
in several keys including:
- Bb major (Cm7 - F7 - BbM7)
- Gb major (Abm7 - Db7 - GbM7)
- D major (Em7 - A7 - DM7)
- F major (Gm7 - C7 - FM7)
But there really doesn't seem to be too much to connect these nor does it seem to be very sequence like and it does not seem to be a full modulation away from F major due to you not staying in one tonal center for too long.
So my questions are:
- What is harmonically going on in the B section of this song?
- How would we reflect this in Roman Numeral analysis?
