This compilation of complex and unconventional chord voicings serves as a valuable resource for musicians, particularly guitarists and pianists, seeking to expand their harmonic vocabulary. It typically presents diagrams and notations for chords beyond standard triads and seventh chords, often including extended and altered harmonies. An example might be a chord diagram illustrating a specific fingering for a Cmaj9(#11) chord on the guitar fretboard.
Such a resource offers significant advantages for enhancing musical creativity and sophistication. By providing access to a wider range of harmonic possibilities, it empowers musicians to craft richer, more nuanced compositions and improvisations. Historically, these types of resources emerged from a desire to codify and share complex harmonic language often found in jazz, modern classical, and other sophisticated musical genres. They represent a distillation of musical knowledge, enabling musicians to study and apply advanced harmonic concepts.
