![]() ![]() Note that there is a third between all the notes and that the seventh and any underlying extensions are included in the chords, even if it is not indicated by the chord symbols.Įxtended chords consist of many different notes, and therefore they usually have a dense and dissonant sound. The extensions are the same regardless of which seventh chord that is extended. Below is an example of the three different extensions (highlighted with green notes) for each of these chords: Major thirteenth (including perfect eleventh and major ninth)Īll seventh chords can be extended, but the most common extended chords are major seventh, dominant seventh, and minor seventh chords. There are three different extensions: Extension Triad with a major second instead of a thirdĪn extended chord is a seventh chord that is extended by one or more notes above the seventh. Triad with a perfect fourth instead of a third Use the chart below to reference the two common types of suspended chords. ![]() Usually, the bass note determines how the chord is interpreted. For example, C sus4 ( C, F, and G) consists of the same notes as F sus2 ( F, G, and C). NameĪ sus4 chord consists of the same notes as a sus2 chord with a root note a perfect fifth below. Use the chart below to reference the two common types of sixth chords. If the bass note is C, normally the chord is interpreted as a chord with C as the root note (e.g. Usually, it is the bass note that determines how the chord is interpreted. Likewise, a minor sixth chord consists of the same notes as a half-diminished seventh chord. For example, the chord C 6 ( C, E, G, and A) consists of the same notes as Am 7 ( A, C, E, and G). A major sixth falls two half steps above the perfect fifth.Ī major sixth chord consists of the same notes as a minor seventh chord. For example, a major sixth chord consists of a major triad and a major sixth. Final remarksīoth types of sixth chords consist of a triad and a major sixth. Some examples of minor sixth chords are Gm 6, E ♭ – 6, and F ♯m 6. The chord symbol for a minor sixth chord is the root note followed by the text ‘m6’ or in jazz sometimes ‘–6’. It has been especially common in jazz since the first half of the 20th century, and classical music since the 19th century. Nameĭiminished triad with a diminished seventhĪ minor sixth chord usually has a minor-like and dissonant sound. Use the chart below to reference the five common types of seventh chords. Diminished major seventh chord (diminished triad with a major seventh).Augmented major seventh chord (augmented triad with a major seventh). ![]() Augmented seventh chord (augmented triad with a minor seventh).Minor major seventh chord (minor triad with a major seventh).In addition to the five common types of seventh chords, there are four seventh chords that are sometimes used, especially in jazz. A major, minor, and diminished seventh fall respectively 1, 2, and 3 half steps below the octave. For example, a major seventh chord consists of a major triad and a major seventh. Final remarksĪll five types of seventh chords consist of a triad and a seventh. For example, C o7 is enharmonic to E ♭ o7, G ♭ o7, and A o7. In the example above, the note B ♭ ♭ is enharmonic to the note A, and should be notated as a diminished seventh, so the notes fall a third apart, as in the above example.Ī diminished seventh chord is enharmonic to several other diminished seventh chords, as each note in the chord can form the root note of a new chord. The diminished seventh in the diminished seventh chord is enharmonic to a major sixth. Please note that some write diminished seventh chords without the number 7, i.e., the same way as diminished triads. Some examples of diminished seventh chords are C o7, D ♭ dim7, and C ♯ o7. The chord symbol for a diminished seventh chord is the root note followed by ‘o7’ or the text ‘dim7’. It is common in classical and popular music, but especially jazz, in most parts of the world. A diminished seventh chord usually has a tense, dissonant, and dense sound. ![]()
