Secondary dominant with barbershop seventh chords. V/V - V - I in F major (G7-C7-F). Derived from [1]. In just intonation. Sevenths are harmonic sevenths, and the F in the first measure is 27.26 cents lower than the F in the third measure. Pitch bend matches intervals.
An important subtype of the descending 5-6 sequence is the root position variant, also known as the Pachelbel sequence, due to the use of this sequence in Pachelbel's Canon. The Pachelbel sequence changes the first inversion chords in the descending 5-6 sequence to root position chords, resulting in a bass pattern that moves down a fourth, and then up stepwise.
The standard way of filling in this descending thirds pattern is to interpolate a first inversion chord in between each of these descents by thirds. The result is a bass line that moves down continuously stepwise, resulting in a figured bass of '5-6', and therefore, the standard descending 5-6 sequence.
