"Giant Steps" Analysis
Most people treat "Giant Steps" as a disjointed collection of ii-V7-I and V7-I changes.
To properly analyze this tune, it must be done in 2/4 time (NOT 4/4).
Here is the genesis of how it was written:
There was/is a very popular Jazz exercise that does a ii-V7-I progression and then begins the next ii-V7-I in the sequence with a minor with the same name as the Major just before it. This runs through six keys before it returns to its starting point.
| Fm| Bb7 | EbMaj7 | EbMaj7 |
| Ebm7| Ab7 | DbMaj7 | DbMaj7 |
| C#m| F#7 | BMaj7|BMaj7 |
| Bm| E7| AMaj7 |AMaj7|
| Am| D7| GMaj7 |GMaj7|
| Gm| C7 | FMaj7 |FMaj7|
This yields a never ending progression whose tonal center goes down a whole step each time.
Coltrane decided to alter this "exercise" with some tritone substitutions.
