It's the second tune that is the topic today. In the liner notes, Ferrell reproduces what I take to be the version he says he "found in one of Tommy [Doucet's] old hand-written dance folios." Two contrasting (that is, motivically largely unrelated) strains of 8 bars each close with PACs in the main key, F major. The first strain is entirely diatonic, whereas the second indulges in some slightly unusual chromaticism: cadence to vi (D minor) in bars 11-12, a fully diminished seventh chord in bar 14, and a chromatic ascent in the cadence.
At (a), the violinistic frame of the fifth is established, at (b) it is expanded in both directions: from C5 to F5 upward and F4 to C4 downwards (arrows). At (c), the common one-too-far gesture reaches A5. At (d), the three unfolded thirds that follow from this. At (e), the consequent phrase begins; at (f), the closing figure: ^8-^7-^9-^8, as F5-E5-G5-F5; at (g) the "boundary play" of the upper thirds.
In the second strain, a "mirror Urlinie" where ^8 descends to ^5 -- line from (a) -- then ascends again to close -- line at (b). In both instances, the chromatic figures sit between ^5 and ^6.
