Augmented fifth on C. In Western classical music, an augmented fifth (Play ⓘ) is an interval produced by widening a perfect fifth by a chromatic semitone. [1] [3] For instance, the interval from C to G is a perfect fifth, seven semitones wide, and both the intervals from C ♭ to G, and from C to G ♯ are augmented fifths, spanning eight semitones.
In the theory and practice of music, a fifth interval is an ordered pair of notes that are separated by an interval of 6–8 semitones. There are three types of fifth intervals, namely perfect fifths (7 semitones), diminished fifth (6 semitones), and; augmented fifth (8 semitones).
In classical music from Western culture, a fifth is the interval from the first to the last of the first five consecutive notes in a diatonic scale. [2] The perfect fifth (often abbreviated P5) spans seven semitones, while the diminished fifth spans six and the augmented fifth spans eight semitones. For example, the interval from C to G is a ...
An augmented triad is a chord, made up of two major thirds (an augmented fifth). The term augmented triad arises from an augmented triad being considered a major chord whose top note (fifth) is raised. When using popular-music symbols, it is indicated by the symbol "+" or "aug". For example, the augmented triad built on A ♭, written as A ...
augmented triads contain a major third, and augmented fifth, symbolized: R 3 ♯ 5 (or 0–4–8) play ⓘ The above definitions spell out the interval of each note above the root. Since triads are constructed of stacked thirds, they can be alternatively defined as follows:
In this case, the chord is viewed as a C major seventh chord (CM 7) in which the third note is an augmented fifth from root (G ♯), rather than a perfect fifth from root (G). All chord names and symbols including altered fifths, i.e., augmented (♯ 5, +5, aug5) or diminished (♭ 5, o 5, dim5) fifths can be interpreted in a similar way.
Augmented dominant seventh chord on C. 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]
This scale is commonly used to improvise over an altered dominant chord. In the section on basic dominant chords, it was noted that the perfect fifth is often omitted. By altering it with a diminished fifth (♭ 5) or augmented fifth (♯ 5), extra tension and dissonance is added, which strengthens the resolution to the I chord. [6]
