Augmented triad
Note count

Brief character
Unstable sound with a sense of unresolved motion. Symmetric structure of major thirds creates a "suspended" sound without clear pull.
Character & mood

Unstable, expanding, "suspended". Ambiguity, tense anticipation of resolution.

Recognition

Recognized by the characteristic "expanding" feel of the augmented fifth.

On the piano

An arpeggio is a broken chord: the same notes played one after another rather than together, bottom-up and back. On the piano they are usually split between the two hands — in an accompaniment, for instance, the left hand carries the bass while the right fills in the figuration.

Any chord can be played arpeggiato or turned into figuration — a broken bass, Alberti figures, a waltz accompaniment. Unlike the guitar, where an arpeggio is tied to the order the strings are plucked, there is no fixed fingering “shape” here — evenness and legato between the notes matter most.

Chord basis

Distinction from similar

Differs from major by the raised fifth (#5 instead of 5).

Function and tensions

Resolution
Dbaugsource
Dbresolves to
Augmented Dbaug has a raised 5th. As a dominant it resolves up a 4th — the raised 5th rising a semitone. Returning to the major of the same root, it instead falls back to a perfect 5th.
Harmonic behavior

Chromatic dominant, transition between major and minor.

Stability note

Transitional — heard as incomplete motion.

Harmonic context

Chords and functions

Degree III of harmonic minor, or a raised fifth degree acting as a chromatic dominant.

Bbmharmonic minor
Dbaugdegree III
The raised 7th of harmonic minor makes the III triad augmented — Dbaug arises within the key on its own.
DbaugV+
F#resolution
As a dominant it resolves a fourth up: the raised fifth (A) rises a semitone into the tonic's third (Bb).
Best harmonies

Harmonic minor, melodic minor, whole-tone scale.

Solo support

Adds an unexpected "twist" to the melodic line.
