The primary symbols used to denote an augmented chord are the plus sign (+) or the abbreviation (aug).
An augmented chord is a type of triad characterized by a major third and an augmented fifth above its root. To indicate an augmented quality in chord symbols, specific notations are appended directly after the root note of the chord.
Common Symbols for Augmented Chords
The table below summarizes the common symbols used for augmented triads, illustrating their application with a hypothetical root of 'C'.
| Chord Quality | Chord Symbol (for a chord with a root of C) |
|---|---|
| Augmented | C+, Caug |
Practical Application and Examples
When writing or reading chord symbols, these notations clearly communicate the augmented quality of a chord.
- To indicate an A augmented chord, you would write A+ or Aaug.

These symbols are universally recognized in music theory and practical musicianship, allowing for clear and concise communication of chord qualities.
Key Takeaways
- The plus sign (+) is a widely used and concise symbol for augmented chords.
- The abbreviation aug also clearly denotes an augmented quality.
- These symbols are always placed immediately after the root note of the chord.
