00:00 A The opening theme centers around the tonic (D flat) with upper and lower neighbor tones, then continues the sequential pattern downward in a line that includes the lowered seventh and the raised fourth. This is a characteristic sound of music of the sertão (backlands) in both the caipira and Northeastern styles.
00:16 B This theme begins with an ascending three-note scalar motive harmonized in thirds and sixths. After the initial motive, a new motive with repeated thirds separated by a step is punctuated by a knock on the body of the viola.
00:41 C This theme begins with a quick upward A flat arpeggio followed by a descending scalar passage decorated with upper-neighbor tones.
00: 51 D This theme also begins with an upward arpeggio, but alters the A flat major sound to minor.
01:01 C repeated
01:11 D repeated
02:02 E This theme introduces a new rhythmic motive and the lowered seventh and raised fourth scale degrees.
2:16 F A quieter, chordal passage played on the upper strings.
03:11 Final two chords are struck.
