The relationship between chords and scales.

Understanding harmony is more than memorizing chord shapes or scale patterns—it’s learning how they work together.
The HGB6 Chord-Scale Harmony library explores the relationship between chords and the scales that generate them. Each worksheet pairs carefully selected HGB6 chord voicings with their corresponding scale, helping you visualize harmony across the fretboard while developing a deeper understanding of improvisation, accompaniment, and composition.
Organized by harmonic families, these studies progress from fundamental major and minor harmony to advanced modal, altered, and symmetrical concepts. Whether you’re building jazz vocabulary or expanding your overall musicianship, these worksheets provide a structured path for connecting theory with practical playing.
The major ii–V–I progression is the foundation of tonal jazz harmony. These worksheets demonstrate how the major scale generates the chords most commonly found in jazz standards while developing guide-tone movement, voice leading, and functional harmonic awareness. Mastering this section provides the vocabulary used throughout countless songs.






Minor ii–V–i progressions introduce the rich harmonic colors of the harmonic minor system. These studies explore the relationship between half-diminished chords, altered dominants, and minor tonic resolution, providing the essential vocabulary for understanding minor-key harmony in jazz and contemporary music.





Minor harmony extends beyond a single sound. These worksheets compare harmonic minor and melodic minor through tonic minor chord families such as minor-major seventh and minor sixth chords. Exploring these harmonic colors develops a broader understanding of modern jazz harmony and expands your expressive vocabulary.
