In one of the subplots (if we can dignify them with that term), Rosalinde's maid Adele aspires to be a professional singer and actress. During the evening party, she comes to believe that Frank (the warden disguised as a marquis) can help her. The following morning (we are now in Act III), she and her sister show up at the jail. In n14, the couplets "Spiel' ich die Unschuld vom Lande," Adele presses her point. Musically, she shows off a variety of styles within a compact form.
A1 8 bars — for the naïf from the countryside, a 6/8 tune like a contredanse gigue, one of the types that had become identified as French folk song by the later 19th century.
A2 8 bars with 4-bar extension (on V)
B1 8 bars closes on tonic -- the second from section
B2 12 bars coda, repeats 4 bar phrase of A1
C 8 bars meno mosso in 3/4 — leads to a bit of a waltz at the end. Adele makes the point of her varied skills.
2 bars transition
D1 8 bars Tempo di marcia -- "Spiel' ich eine Königin" (for the queen, a regal march)
1 bar intro
D2 8 bars
D2 repeat with Ida and Frank
C reprise
repeat 2 bars transition
E1 10 bars 2/4 Allegretto grazioso. "Spiel ich 'ne Dame von Paris" (for the lady of Paris, a 2/4 grazioso--these have their source in the 18th century contredanse-gavotte and remain a staple as late as film music underscore in the 1940s)
E2 8 bars
F 12 bars
E2’ 9 bars; with cadence to tonic
The music of interest to us here is in sections D and E/F. The 8-bar consequent of D finishes with a descending but open cadence. The focal tone is ^5 (as D5); in the cadence this moves to ^4 (C5) and one then imagines ^3 (B4). (So, an unfolded third C5-A4 to the third G4-[B4]).
In the repeat of the consequent--with added sound effects from Ida (Adele's sister) and Frank--Adele takes the focal tone ^5 up to ^7 and ^8 (F#5-G5) in the cadence:
In the analogous place in the E theme (specifically, the repeat of it that closes the aria), the focal tone is again ^5 (D5), the singer takes it up through D#5 to E5 over the cadential ii6, then substitutes ^5 for ^7, while the orchestra provides the ^7:
