About This Standard
Composed by John Coltrane and recorded in 1959 for the album Giant Steps (released 1960), this landmark piece introduced what became known as "Coltrane changes" — a system of cycling major thirds that divided the octave into three equal parts. It represented a complete break from traditional jazz harmony and remains one of the most studied and discussed compositions in jazz.

Harmonic Analysis
Giant Steps cycles through three key centers a major third apart: B major, G major, and Eb major — each a major third (4 semitones) away from the next. These three keys divide the octave into equal thirds, creating a symmetrical harmonic system. The changes move at two chords per bar in a 16-bar form, cycling B major→D7→G major→Bb7→Eb major→Am7 D7→G major, etc. At the original fast tempo (≈ 286 BPM), navigating these key centers demands complete fluency in ii-V-I patterns in B, G, and Eb simultaneously.
