A major chord is a triad with a major third and a perfect fifth above the root. The major chord above C is spelled C–E–G.
The primary intervals in a major chord are the major third between the first and second notes, the perfect fifth between the first and third notes, and the minor third between the second and third notes.[1] It is a tertian chord, because it is built in thirds.[4] When the root of the chord is not in the bass, the chord is considered inverted.[5] In integer notation, a major triad is {0,4,7}.[6]
On lead sheets, a major chord is indicated by the letter of its root (and any relevant accidental).[7]
The major chord timbre is sometimes described as brighter than its minor counterpart.[8]
In just intonation, a major chord is tuned to the frequency ratio 4:5:6. The just major scale contains major triads at I, IV, and V.[10] In equal temperament, the fifth is two cents narrower than the just perfect fifth, and the major third is 14 cents narrower than the just major third.[11]

A major chord is a triad with a major third and a perfect fifth above the root. The major chord above C is spelled C–E–G.
In music, a major seventh chord is a seventh chord in which the third is a major third above the root and the seventh is a major seventh above the root. The major seventh chord, sometimes also called a Delta chord, can be written as maj7, M7, Δ, ⑦, etc. The "7" does not have to be superscripted, but if it is, then any alterations, added tones, or omissions are usually also superscripted. For example, the major seventh chord built on C, commonly written as Cmaj7, has pitches C–E–G–B: It can be represented by the integer notation {0, 4, 7, 11}. According to Forte, the major seventh chord is exemplified by IV7, which originates melodically. The just major seventh chord is tuned in the ratios 8:10:12:15, as a just major chord is tuned 4:5:6 and a just major seventh is tuned 15:8. The minor flat sixth chord (minor triad with an added minor sixth) is an inversion of this chord.
In music, an augmented major seventh chord or major seventh sharp five chord is a seventh chord composed of a root, major third, augmented fifth, and major seventh (1, 3, ♯5, 7). It can be viewed as an augmented triad with an additional major seventh. When using popular-music symbols, it is denoted by e.g. +Δ7. For example, the augmented major seventh chord built on A♭, written as e.g. A♭+Δ7, has pitches A♭-C-E-G: The chord can be represented by the integer notation {0, 4, 8, 11}. The augmented major seventh chord is associated with the augmented scale (see jazz scale and chord-scale system). This chord also comes from the third mode of both the harmonic minor and the melodic minor scales. For example, the third mode of the A melodic minor scale outlines an augmented major seventh chord, as shown below. As with dominant seventh chords, nondominant seventh chords including the augmented major seventh usually progress according to the circle, thus III+M7 resolves to vi or VI. For example, in the key of A minor, C maj7♯5 usually resolves to F.
A minor major seventh chord, or minor/major seventh chord is a seventh chord composed of a root, minor third, perfect fifth, and major seventh (1, ♭3, 5, and 7). It can be viewed as a minor triad with an additional major seventh. When using popular-music symbols, it is denoted by e.g. m(M7). For example, the minor major seventh chord built on A, written as e.g. Am(M7), has pitches A–C–E–G♯: The chord can be represented by the integer notation {0, 3, 7, 11}.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
