Giant Steps

Giant Steps revolutionized jazz harmony with “Coltrane Changes,” a system of key shifts a major third apart that took musicians years to master. John Coltrane’s 1960 Atlantic Records album cycles through three key centers at a blistering 300 bpm, making it 40% more harmonically dense than the typical hard bop album. The title track’s complexity surpasses even Head Hunters in technical ambition, and its influence on jazz theory is measurable: over 500 academic papers cite its chord progressions.
