What is a Major Seventh Chord?

A major seventh chord is a type of four-note chord built from a root, a major third, a perfect fifth, and a major seventh. These notes are stacked in intervals of thirds to create a rich and smooth harmonic sound. For example, a C major seventh chord (Cmaj7) consists of the notes C, E, G, and B.

The defining feature of a major seventh chord is the interval between the root and the seventh, which is a major seventh. This interval gives the chord a bright and sophisticated sound that is often described as smooth, warm, or jazzy. Because of its expressive quality, the chord adds color and depth compared to a simple major triad.

Major seventh chords are commonly used in jazz, soul, R&B, and modern pop music. They are often used to create relaxed and atmospheric harmonies in chord progressions. In many musical styles, the major seventh chord helps add richness and emotional nuance to melodies and harmonic arrangements.
