A♭ Major Seventh Chord
Abmaj7 is a Ab major seventh chord — one of the most widely used chords in contemporary music. Warm, luminous, and emotionally open, it appears in jazz, gospel, neo-soul, R&B, pop, and worship music wherever a sophisticated but approachable sound is needed.
The major seventh chord adds a major seventh interval (11 semitones) above the root to a major triad. Abmaj7 uses the notes Ab, C, Eb, G. The major seventh (G) creates a gentle tension with the root — close enough to sound warm but far enough to feel sophisticated. The interval between the major seventh and the root (just one semitone away) gives the chord its characteristic "floating" quality. In functional harmony, the major seventh chord serves as the tonic (I) or subdominant (IV) chord, both of which provide a sense of rest or lift without the finality of a plain triad.

Major chords are the bright foundation of Western harmony — stable, resolved, and immediately recognizable. Their structure (root, major third, perfect fifth) creates a sound that feels complete and confident, like a musical declaration of "yes."

For a classic jazz voicing, try root–third–seventh (omitting the fifth). On piano, left hand plays the root and right hand plays third–fifth–seventh. For a fuller sound, add the 9th above the major seventh for a maj9 extension. The major seventh creates a half-step dissonance with the octave root — keep it voiced apart for clarity.
