Major Sixth Chord

The chord formula for the major sixth chord is 1, 3, 5, 6 of a major scale. It is indicated by a root name and 6. For our purposes, for all major quality chords the 6th is assumed, therefore the symbols C, and C Maj both indicate C6 (C, E, G, and A)

Diminished Seventh Chord

The chord formula for the diminished seventh chord is 1, b3, b5, 6 (bb7) relative to the scale degrees of a major scale. It is indicated by a root name, dim, and 7. Notes of diminished seventh chords are often spelled enharmonically for ease of identification.

The letter name of a chord symbol is always the root of the chord.

D min 7 (D is the root of the chord).
G7 (G is the root of the chord).
C Maj 7 (C is the root of the chord).

A chord includes the pitch a major third above the root of the chord unless the third is "qualified" by the chord symbol. Qualifiers that affect the third always lower it a half step creating a minor third above the root. Minor, diminished, and half diminished are the qualifiers that lower the third. The preferred abbreviations are min and dim.

C7 (E is the third of the chord because it is not "qualified" by the chord symbol).
C min 7 (Eb is the third of the chord because it has been "qualified" or lowered by the chord symbol.)
A Maj 7 (C# is the third of the chord).
A dim 7 (C is the third of the chord).

A chord includes the pitch a perfect fifth above the root of the chord unless "qualified" by the chord symbol. Qualifiers that affect the fifth raise the fifth a half step (augmented fifth) or lower the fifth (diminished fifth). Augmented is the "qualifier" that raises the fifth. Diminished, half diminished, and flat five are qualifiers that lower the fifth. The preferred abbreviations are Aug, dim, and b5.

C Maj 7 (G is the fifth of the chord).
C Aug 7 (G# is the fifth of the chord).
C dim 7 (Gb is the fifth of the chord. Note that when dim is part of the chord symbol the third is also lowered).
C min 7 (b5) (Gb is the fifth of the chord. Note that when min is part of the chord symbol the third is also lowered).

A chord includes the pitch a major sixth above the root of the chord when the numeral 6 is part of the chord symbol.

F6 (D is the sixth of the chord).
F min 6 (D is the sixth of the chord).

For all major quality chords, the 6th is assumed unless otherwise notated. The symbols C, and C Maj both indicate C6 (C, E, G, and A)

For all major quality chords, the 6th is assumed unless otherwise notated. The symbols C, and C Maj both indicate C6 (C, E, G, and A)

A chord includes the pitch a minor seventh above the root of the chord (subtonic) unless the seventh is "qualified" by the chord symbol. Qualifiers that affect the seventh raise the seventh a half step (major seventh) or lower the seventh a half step (diminished seventh). Major 7 is the qualifier that raises the seventh. Diminished seven is the qualifier that lowers the seventh (the diminished seventh may be spelled enharmonically as the major sixth). The preferred abbreviations are Maj 7 and dim 7.

G7 (F is the seventh of the chord).
G Maj 7 (F# is the seventh of the chord).
Bb7 (Ab is the seventh of the chord).
Bb dim 7 (Abb or G is the seventh of the chord. Note that with dim as a part of the chord symbol the third and the fifth are also lowered).
