The minor third is a foundational interval in jazz, defining minor tonality, blues inflection, and sophisticated harmonic substitutions. This article explores its notation, performance, theoretical role, historical context, and enduring influence in jazz harmony.
Guide-tone voice leading is a jazz harmony technique that prioritizes the 3rd and 7th of each chord—known as guide tones—to create smooth, stepwise melodic motion between harmonies. By focusing on these tones, musicians achieve cohesive and expressive progressions that define chord quality and drive harmonic rhythm. This article explores the definition, historical roots, practical application, and enduring influence of guide-tone voice leading in jazz and beyond.
