Music Theory QuickThink: 

-          Augmented sixth chords contain the interval of an augmented sixth (usually above the bass)

-          The augmented sixth is formed by the lowered sixth scaled degree, b6, and the raised fourth scale degree, #4

-          Using moveable do sol fege, these degrees are referred to as ‘le’ and ‘fi’ 

-          The German Augmented 6th involves the the pitches ‘le’, ‘fi’ , ‘do’ , and ‘me’ (b3)

-          NOTE: b6/le and b3/me do not mean to lower the 6th or 3rd scale degrees, but rather to ‘le’ and ‘me’ in relationship to ‘do’ (if you are in a minor key, the 6th scale degree of the natural minor scale is already ‘le’ and the 3rd scale degree is already ‘me’)

-          NOTE: In major keys, 'me' can be rewritten as 'ri' to provide for a different voice leading following the chord.

-          German augmented-sixth chords are often marked as  Gr6

-          Gr6 chords serve a predominant function, thus are usually followed by a dominant functioning chord

-          Example, key of ‘a minor’ , Gr6 = F, D#, A, C  (F in the bass)
