Encyclopedia > Augmented chord

In general, an augmented chord is any chord which contains an augmented interval. An augmented sixth chord, for instance, has an augmented sixth between the highest and lowest notes. More specifically, the augmented chord is the three-note chord consisting of a major third and augmented fifth above the root - if the root is C, the augmented chord consists of the notes C, E and G sharp. It can also be thought of as two major thirds stacked on top of one another, and thus resembles a major chord with a raised fifth. This particular chord is also known as the augmented triad. In music and music theory, a chord (from the middle English cord, short for accord) is three or more different notes or pitches sounding simultaneously, or nearly simultaneously, over a period of time. ... In music and music theory augmentation is the lengthening or widening of rhythms, melodies, intervals, chords. ... In music theory, an interval is the distance in pitch between two notes, the lower and higher members of the interval. ... An augmented sixth chord is a chord which has the interval of an augmented sixth between its highest and lowest notes and also a major third above the lowest note. ... The musical interval of a Major third is the relationship between the first note (the root or tonic) and the third note in a major scale. ... The musical interval of a minor sixth is the relationship between the first note (the root or tonic) and the sixth note in a minor scale. ... The root (basse fondamentale) of a chord is the note upon which that chord is perceived or labelled as built or centered, the root of a chord in root position or normal form. ... Generally speaking, a major chord is any chord which has a major third above its root, as opposed to a minor chord which has a minor third. ... In music or music theory, a triad is a tonal or diatonic tertian trichord. ...


In twelve tone equal tempered tuning, an augmented chord has 4 semitones between the third and fifth, 4 between the root and third, and 8 between the root and fifth. It is represented by the integer notation 0,4,8. Equal temperament is a scheme of musical tuning in which the octave is divided into a series of equal steps (equal frequency ratios). ... The musical interval of a half step, semitone, or minor second is the relationship between the leading tone and the first note (the root or tonic) in a major scale. ...


The augmented chord is considered dissonant, or unstable, and lacks tonal center or drive. It symmetrically divides the octave and is ambiguous as to root because an augmented chord built from any note of an augmented chord produces that same chord. In poetry, dissonance is the deliberate avoidance of patterns of repeated vowel sounds (see assonance). ... Tonality is the character of music written with hierarchical relationships of pitches, rhythms, and chords to a center or tonic. ... Square with symmetry group D4 Symmetry is a characteristic of geometrical shapes, equations, and other objects; we say that such an object is symmetric with respect to a given operation if this operation, when applied to the object, does not appear to change it. ... In music, an octave (sometimes abbreviated 8ve or 8va) is the interval between one musical note and another with half or double the frequency. ... The root (basse fondamentale) of a chord is the note upon which that chord is perceived or labelled as built or centered, the root of a chord in root position or normal form. ...

The augmented chord is considered dissonant, or unstable, and lacks tonal center or drive.
This chord precedes a diatonic triad, and is its dominant, or its VIIo (the leading-tone triad, or VIIo7, the leading-tone seventh chord).
The chord represents an chromatic modification of the the IV6 in the so-called "Phrygian" cadence.

The prefix 'augmented' identifies it as being the largest of the three intervals; the others being the perfect fifth and diminished fifth, which are one and two semitones smaller, respectively.
The prefix 'augmented' identifies it as being the largest of the three intervals; the others being the perfect fifth and diminished fifth, which are one and two chromatic semitones smaller, respectively.
The note determining the functional identity of the chord is the seventh of the dominant 7th and the "root" of the German 6/5 (the note that usually appears in the soprano and forms the interval of the augmented sixth with the bass).
