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 movable do sol fege, these degrees are referred to as ‘le’ and ‘fi’ 

-          The French Augmented 6th involves the the pitches ‘le’, ‘fi’ , ‘do’ , and ‘re’ (^2)

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

-          French augmented-sixth chords are often marked as  Fr6

-          Fr6 chords serve a predominant function, thus are usually followed by a dominant functioning chord

-          Example, key of ‘a minor’ , Fr6 = F, D#, A, B  (F in the bass)
