- 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’
- NOTE: b6 and le do not mean to lower the 6th scale degree, but rather
to ‘le’ in relationship to ‘do’ (if you are in a minor key, the 6th scaled degree
of the natural minor scale is already ‘le’)
- The Italian augmented-sixth chord is a triad involving the pitches ‘le’,
‘fi’ and ‘do’
- - Italian augmented-sixth chords are often marked as It6
- It6 chords serve a predominant function, thus are usually followed by
a dominant functioning chord
- ‘Do’ is usually doubled in an It6 chord
- Example, key of ‘a minor’ , It6 = F, D#, A (F in the bass)
