Sinfonía india is Carlos Chávez's Symphony No. 2, composed in 1935–36. In a single movement, its sections nevertheless follow the traditional pattern for a three-movement symphony. The title signifies the fact that the thematic material consists of three melodies originating from native-American tribes of northern Mexico. The symphony is Chávez's most popular composition.
The Sinfonía india was begun in December 1935, during the composer's first tour of the United States as a conductor, and finished early in the following year. It was premiered under Chávez's direction in a radio performance by the Columbia Broadcasting Orchestra on 23 January 1936, and given its first concert performance by the Boston Symphony Orchestra conducted by the composer on 10 April 1936. The Mexican premiere took place in the capital on 31 July 1936 (Slonimsky 1945, 234).
This symphony has become immensely popular, and so the primary source of the composer's identity with the public, comparable in this respect with Beethoven's Fifth Symphony and Ravel's Bolero (Parker 1983, 70).
In 1971 G. Schirmer, the publisher of the work, issued an arrangement for wind band by Frank Erickson. Although Chávez had not authorised this version, he did conduct it himself in performances, though with some revisions of his own (Parker 1983, 72).
The symphony is scored for two piccolos (the second interchangeable with third flute), two flutes, three oboes, E♭ clarinet, two clarinets, bass clarinet, three bassoons, four horns, two trumpets, two trombones, timpani, percussion (four players), harp, and strings.
The percussion section originally included a large number of indigenous Mexican instruments, for example the jicara de agua (half of a gourd inverted and partly submerged in a basin of water, struck with sticks), güiro, cascabeles (a pellet rattle), tenabari (a string of butterfly cocoons), a pair of teponaxtles, tlapanhuéhuetl, and grijutian (string of deer hooves). When the score was published, the composer substituted their nearest equivalents in commonly used orchestral percussion, but requested that the originals be used wherever possible (Chávez 1950; García Morillo 1960, 91; Slonimsky 1945, 44, 216, 234).
