The structure of the four-bar ground is: quartal triad; augmented triad; 7th triad; major triad. A few rhythmic twists aside, this trio will not prove searchingly difficult for intermediate players. In bb. 44-5, the alto plays a Db, combining flutter tonguing and finger vibrato; before quitting the note, however, only the vibrato persists. Duration: 1:50
