The augmented seventh chord, or seventh augmented fifth chord, [1] or seventh sharp five chord is a seventh chord composed of a root, major third, augmented fifth, and minor seventh (1, 3, ♯ 5, ♭ 7). [2] It can be viewed as an augmented triad with a minor seventh. [3] When using popular-music symbols, it is denoted by + 7, aug 7, [2] or 7♯5.
Augmented major seventh 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.
the root note (e.g. C ♯) the chord quality (e.g. minor or lowercase m, or the symbols o or + for diminished and augmented chords, respectively; chord quality is usually omitted for major chords) whether the chord is a triad, seventh chord, or an extended chord (e.g. Δ7) any altered notes (e.g. sharp five, or ♯ 5)
The most common chords are tertian, constructed using a sequence of major thirds (spanning 4 semitones) and/or minor thirds (3 semitones). Since there are 3 third intervals in a seventh chord (4 notes) and each can be major or minor, there are 7 possible permutations (the 8th one, consisted of four major thirds, results in a non-seventh augmented chord, since a major third equally divides the ...
Play ⓘ. In classical music from Western culture, an augmented seventh is an interval produced by widening a major seventh by a chromatic semitone. For instance, the interval from C up to B is a major seventh, eleven semitones wide, and both the intervals from C ♭ up to B, and from C up to B ♯ are augmented sevenths, spanning twelve semitones.
Chord (music) In music, a chord is a group of two or more notes played simultaneously, typically consisting of a root note, a third, and a fifth. [a] Chords are the building blocks of harmony and form the harmonic foundation of a piece of music. They can be major, minor, diminished, augmented, or extended, depending on the intervals between the ...
The harmonic minor scale (or Aeolian ♮7 scale) is a musical scale derived from the natural minor scale, with the minor seventh degree raised by one semitone to a major seventh, [2][3][4] creating an augmented second between the sixth and seventh degrees. Thus, a harmonic minor scale is represented by the following notation: A harmonic minor ...
An altered seventh chord is a seventh chord with one, or all, [15] of its factors raised or lowered by a semitone (altered), for example, the augmented seventh chord (7+ or 7+5) featuring a raised fifth (C E G ♯ B ♭ [16] (C 7+5: C–E–G ♯ –B ♭). The factors most likely to be altered are the fifth, then the ninth, then the thirteenth ...
