3) Online Reading: Augmented 6th chords, http://legacy.earlham.edu/~tobeyfo/musictheory/Book2/FFH2_CH6/6C_Augmented6th.html
- 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)
