The Abmaj7 chord
Start with the recipe. The notes are Ab - C - Eb - G, a major seventh, otherwise known as the Abmaj7. The chord feels a major chord with a wistful halo, which is why writers chasing a jazz-pop sheen keep landing on it. You will find it inside jazz standards, lo-fi beats and indie ballads. The rest of this page lays out the common voicings, the interval theory, the progressions where the chord fits, and the records that lean on it for structural work.
