The sixth of these pieces is a duet for flute and bassoon meant to evoke serenades commonly written (15[1])for flute (15[2])and ophicleide. The last of these pieces, different versions of which were written for chorus and string orchestra, (15[1])closes with a fugue in 11/8 time (15[1])that ends on a unison C. In one of these pieces, a vocalist imitates birdsong by singing “Lia! Lia!” after listing off various bird species. Many movements of these pieces are given two different names, such as a “Chorale” in no. 4 alternately titled “Song of the (*) Hinterlands.” The fifth of these pieces is written for 8 cellos (10[1])and a solo soprano, (10[1]-5[1])and (10[1])the second 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. ■END■ (10[1])
