an augmented chord is a major triad (1 3 5) with a raised fifth (i.e. 1 3 5#).
the term used to describe the process of increasing an interval, for example C to G is a fifth but C to G# is an augmented fifth
refering to either an interval that is one-half step larger than a perfect or a major interval. An augmented triad consists of a major third and an augmented fifth above the root.
Any perfect interval raised one half-tone.
Raised, or enlarged. Generally refers to the raising of a pitch chromatically by one half step.
Raised by a half-step. See 'Alteration'.
when a set of rhythmic values are lengthened; all values may be doubled, for instance. (Intervals may also be augmented, but this rarely happens in medieval music.) Antonym: diminished.
An interval or chord that is one half step smaller than minor or perfect.
An interval that has been widened. A chord is called augmented if it contains an augmented interval. For example, the augmented fifth is a halfstep wider than the perfect fifth, and an augmented chord is a major chord with an augmented fifth replacing the perfect fifth. (See also Diminished, Dominant, Major, Minor, Perfect, Suspended.)
An augmented chord is a major triad with a reaised fifth. Certain intervals raise by a semitone are termed augmented.
