Coltrane Changes - "Giant Steps"

"Giant Steps"

The Giant Steps cycle is the culmination of Coltrane's theories applied to a completely new chord progression: Coltrane uses the Coltrane cycle in ascending Major 3rd tonal transpositions in the opening bars and then ascending ii V I progressions separated by a major 3rd in the second section of Giant Steps. The second section is basically the inverse of the bridge section described in "Have You Met Miss Jones" above.

| I Coltrane Substitution Cycle| ii V | I Coltrane Substitution Cycle| | BM7* D7 | GM7* Bb7 | EbM7* | Am7 D7 | GM7* Bb7 | EbM7* F#7 | BM7* |

Ascending/Descending ii V I progression separated by a Major 3rd (Tonal centers E♭ - G - B - E♭ - B)

| ii V | I | ii V | I | ii V | I | ii V | I | ii V :|| | Fm7 Bb7 | EbM7* | Am7 D7 | GM7* | C#m7 F#7 | BM7* | Fm7 Bb7 | EbM7* | C#m7 F#7 :||

Famous quotes containing the words giant and/or steps:

    The point of the dragonfly’s terrible lip, the giant water bug, birdsong, or the beautiful dazzle and flash of sunlighted minnows, is not that it all fits together like clockwork--for it doesn’t ... but that it all flows so freely wild, like the creek, that it all surges in such a free, finged tangle. Freedom is the world’s water and weather, the world’s nourishment freely given, its soil and sap: and the creator loves pizzazz.
    Annie Dillard (b. 1945)

    All our steps are ordered by the LORD; how then can we understand our own ways?
    Bible: Hebrew, Proverbs 20:24.
