The term "back cycling" is used when discussing reharmonization in jazz. What does the term mean, and what are examples of its use (preferably real-world examples taken from jazz songs)? Can it be used chromatically with tritone subs? Does it only apply to reharmonizations? To what extent does it require dominant seventh chords?
I used to hear it called 'going round the houses', but that was a long, long time ago.
It's basically the circle/cycle of fourths/fifths. Never know exactly what to call that ! it's getting back to the root via each chord going up to the next in fourths.
For example, in C. F#7 B7 / E7 A7 / D7 G7 / Cmaj7 /.
Which can be embellished in a ii-V-I fashion.
F#m7b5 B7b9 / Em7b5 A7b9 / Dm7 G7 / Cmaj7 /.
I guess tts could be used, but don't use them too much myself, although an obvious place could be the penultimate bar, going Dm7 Db7 / Cmaj7 /.
Looking for samples.
Back cycling is finding chords that will lead you to a target chord. This is very useful if you have a chord which lasts for a long duration and you wish to transition to somewhere else. The technique often uses V7 (or tritone substitutitions), so you tend to move aroung the circle of 4th (hence "cycling") and you start from the target chord and move "back".
For instance, consider the following chords grid:
| CMaj7 / / / | CMaj7 / / / | Fm7 / / / |
your target is Fm7. What's the easiest way to get to Fm7? C7 (V7 of Fm). So you can change this to:
| CMaj7 / / / | C7 / / / | Fm7 / / / |
But then how to you get to C7? Easy, use G7 (V7 of C). You get:
| CMaj7 / / / | G7 / C7 / | Fm7 / / / |
And how do you get to G7? For instance, with D7:
| CMaj7 / D7 / | G7 / C7 / | Fm7 / / / |
But you can also use IIm7 V7 instead of using V of V:
| CMaj7 / D7 / | Gm7 / C7 / | Fm7 / / / |
Or tritone substitutions:
| CMaj7 / Ab7 / | Gm7 / C7 / | Fm7 / / / |
| CMaj7 / Ab7 / | Gm7 / Gb7 / | Fm7 / / / |
