At some point, C7 and B♭13 became two of my favorite chords, so I've become interested in some chord progressions that contain these two in succession. I'll outline some ideas and my thoughts on them below:
- F major: contains both the root and major thirds for both C7 and B♭13. However, it also does not contain the A♭ you'd expect in the 13 chord (or so I understand how chord notation like this typically works)
- F (harmonic) minor: this one has an A♭ and an E, but also has a D♭ (so it would become C7, B♭ m13)
- F (melodic) minor: with the chords placed at the right point in the melody, this may be a solution
What all these have in common is C7->B♭13->F (or V7->IV13->I). What would be some other suggested progressions (or ones that reverse the order of the C and a B chords)?
P.S. I added the Jazz tag due to extended chords being much more common in jazz than in other music I play.
