In E-flat major, for instance, beginning with D half-diminished and moving through related chords like D♭ minor 6, C♯ minor 7#5, B major 7, and B♭ minor 7, provides a rich harmonic palette suitable for intros or endings. Adding diminished chords for further tension enhances this approach, offering multiple options for dynamic musical statements.
