What’s an easy way to find out of a chord is an Augmented 6th or Diminished 3rd?
Understanding the Concept
Augmented sixth chords and diminished thirds are terms commonly used in classical harmony. Augmented sixth chords are a group of chromatic predominant chords that contain an augmented sixth interval between two specific notes. On the other hand, diminished thirds refer to a specific interval between two notes.
Analyzing the Chord
To determine whether a chord is an augmented sixth chord or a diminished third chord, it is important to examine the notes in the chord and their relationship to each other. Look for the presence of an augmented sixth interval or a diminished third interval within the chord structure.
Resolution
Consider how the chord resolves. Augmented sixth chords typically resolve to the dominant chord in classical harmony. Pay attention to the movement of the individual voices and the resolution patterns commonly associated with augmented sixth chords. In contrast, diminished thirds may resolve differently depending on the musical context.
Identifying the Type
If the chord contains an augmented sixth interval and resolves to the dominant, it is likely an augmented sixth chord. To determine the specific type of augmented sixth chord, analyze the scale degrees and solfege of the chord. This can provide insights into whether the chord is a German, Italian, or French augmented sixth chord, each with its characteristic voice-leading patterns.
These guidelines can help in identifying whether a chord is an augmented sixth chord or a diminished third chord. By understanding the concept, analyzing the chord’s notes and resolution, and considering the specific type, musicians and theorists can accurately classify and interpret these harmonic structures.

FAQs
What is an augmented sixth chord?
An augmented sixth chord is a type of chromatic predominant chord in classical harmony. It consists of an augmented sixth interval between two specific notes.
How is a diminished third different from an augmented sixth chord?
A diminished third refers to a specific interval between two notes, whereas an augmented sixth chord is a chord that contains an augmented sixth interval. They are distinct concepts in music theory.
How can I analyze a chord to determine if it is an augmented sixth chord or a diminished third chord?
To analyze a chord, examine the notes and their relationships within the chord structure. Look for the presence of an augmented sixth interval or a diminished third interval to identify the type of chord.
What role does resolution play in determining if a chord is an augmented sixth chord or a diminished third chord?
Augmented sixth chords typically resolve to the dominant chord in classical harmony, while diminished thirds may have different resolution patterns depending on the musical context. Considering the resolution can provide clues about the chord’s type.
Are there specific characteristics or voice-leading patterns associated with augmented sixth chords?
Yes, different types of augmented sixth chords, such as German, Italian, and French, have characteristic voice-leading patterns. Analyzing the scale degrees and solfege of the chord can help identify the specific type.
Can an augmented sixth chord contain a diminished third interval?
No, an augmented sixth chord contains an augmented sixth interval, not a diminished third interval. These are distinct harmonic concepts with different interval relationships.
How can understanding augmented sixth chords and diminished thirds enhance my musical analysis?
Understanding these harmonic concepts allows you to accurately classify and interpret chords in classical music. It provides insights into the function, voice-leading, and resolution patterns within a musical composition.
Are augmented sixth chords commonly used in contemporary music?
Augmented sixth chords are more commonly associated with classical music rather than contemporary styles. However, elements of these chords and their voice-leading patterns may still be found in some modern compositions.
