솔리 I (Soli I, for oboe, clarinet, trumpet and bassoon)

Soli I is the first of a series of four works by the Mexican composer Carlos Chávez, each called Soli and each featuring a succession of instrumental solos. Three of these compositions are chamber music, and the remaining one is a sort of concerto grosso for four soloists and orchestra. This first work of the series is a quartet for oboe, clarinet, bassoon, and trumpet. The Solis belong to the more "experimental", high-modernist strand of Chávez's compositional output, in contrast to the more traditional character of most of the large-ensemble works. This group of works, which also includes the three Inventions (No. 1 for piano, 1958; No. 2 for string trio, 1965; No. 3 for harp, 1967) and the orchestral compositions Resonancias (1964), Elatio (1967), Discovery, Clio (both 1969), and Initium (1973), features an abstract, atonal musical language based on the principle of non-repetition. Soli I was Chávez's first attempt at this idea of constant renewal, which avoids traditional techniques of sequence, imitation, development, and structural symmetry in favour of an endlessly unfolding counterpoint. In the composer's own words, the objective is one of "constant rebirth, of true derivation: a stream that never comes back to its source; a stream of eternal development, like a spiral, always linked to, and continuing, its original source, but always searching for new and unlimited spaces".
