In the second movement of the second of these pieces, two largo assai sections surround a central Tempo di marcia section whose opening melody passes from the tenor saxophone to the cello section, then back. The sixth of these pieces is a duet for flute and bassoon meant to evoke serenades commonly written (15[1])for flute and ophicleide. In one of these pieces, a vocalist imitates birdsong by singing “Lia! Lia!” after listing off various bird species. A “Chorale” in the fourth (15[1])of these pieces is alternately titled “Song of the (-5[1])(*) Hinterlands.” The fifth of these pieces is written for 8 cellos and a solo soprano, and the second (10[1])concludes with a toccata depicting the “Little Train of the Caipira.” For 10 points, name this set of pieces that draw on both South American folk music and Baroque counterpoint, written by Heitor Villa-Lobos.
