EbGBbC

EbGBbC is a compact notation referring to a four-note pitch-class collection: E-flat (Eb), G-flat (Gb), B-flat (Bb), and C. When read as a chord, this set corresponds to an E-flat minor triad (Eb-Gb-Bb) with an added major sixth (C), and is commonly notated as Ebm6. The same collection can be enharmonically spelled as D-sharp minor six (D#m6).

In harmonic practice, Ebm6 provides a melancholic, color-rich sonority that fits naturally in minor-key contexts and jazz-inflected modern harmony. It can function as a tonic color chord, a passing sonority within progressions, or as a substitute for related minor chords, depending on the surrounding harmony and voice leading.

Voicings and realizations: On piano, the chord can be voiced in multiple inversions: root position Eb-Gb-Bb-C; first inversion Gb-Bb-C-Eb; second inversion Bb-C-Eb-Gb; third inversion C-Eb-Gb-Bb. On guitar, common approaches outline the same four notes using barre or partial shapes that emphasize the Ebm6 sonority while fitting within a given key or progression.

As a pitch-class set, Eb-Gb-Bb-C is analyzed in terms of its interval content and its role within a larger musical context, such as a progression in minor tonality or as a color chord in jazz arrangements. Outside music theory and chord notation, EbGBbC does not denote a widely recognized distinct entity.
