EbGBbD

EbGBbD is a shorthand listing of four pitch classes: E-flat, G, B-flat, and D. In typical harmony, these notes form an E-flat major seventh chord, written as Ebmaj7 (also EbΔ7). The chord consists of a root on E-flat, a major third up to G, a perfect fifth up to B-flat, and a major seventh up to D.

The interval structure of Ebmaj7 is a major third, followed by a minor third, followed by a major third: Eb to G is a major third, G to Bb is a minor third, and Bb to D is a major third. This combination gives the characteristic smooth, jazzy color associated with major seventh chords. The standard practice is to spell the chord as Eb–G–Bb–D, ensuring the correct interval quality from the root.

Common uses and voicings: Ebmaj7 is widely used in jazz, pop, and soul genres to convey a warm, lush sound. On piano, it can be voiced in close position as Eb–G–Bb–D or with various inversions (G–Bb–D–Eb, Bb–D–Eb–G, D–Eb–G–Bb) to suit voice leading. On guitar, typical shapes place the notes across adjacent strings to achieve a smooth timbre.

Notation and variants: EbGBbD itself is not a standard chord symbol; the conventional name is Ebmaj7 or EbΔ7. Enharmonic spacing may appear in different keys, but the pitch classes Eb, G, Bb, and D remain the defining set of this chord. Extensions such as added 9ths or 13ths yield forms like Ebmaj9 or Ebmaj13, expanding its color.
