Salvador Contreras
Mexican composer (1910-1982)

Salvador Contreras Sánchez (10 November 1910 – 7 November 1982) was a Mexican composer and violinist, a member of the Grupo de los cuatro.
Life
Contreras was born in Cuerámaro, Guanajuato, the son of José Contreras and Nemoria Sánchez. His musical education was at the Mexico City Conservatory, where he studied violin with Silvestre Revueltas, music theory with Candelario Huízar, and composition and conducting with Carlos Chávez. Together with Daniel Ayala Pérez, Blas Galindo, and José Pablo Moncayo, he formed the Grupo de jóvenes compositores in 1935, which later became the Grupo de los cuatro.
Musical style
Contreras's early works from the 1930s and early 1940s were predominantly contrapuntal and neoclassical, with folk-like tunes and brash rhythms. His Obertura en tiempo de danza (Overture in Dance Time, 1942), for example, prominently uses measures in 7/8 and 5/8, which alternate with the more common 2/4 and 3/4. In the mid-1960s he began using serial techniques, allying him with Manuel Enríquez and losing him his former broad public appeal.
Compositions
Among his best-known works are:
Sonata, for violín and cello (1933)
Piece for String Quartet (String Quartet No. 2) (1936)
Música para orquesta sinfónica (1940)
Obertura en tiempo de danza (1942)
Cuatro canciones (1959)
String Quartet No. 3 (1962)
Three Movements for guitar (1963)
Dos piezas dodecafónicas (1966)
Cantata a Juárez (1967)
Seven Preludes, for piano (1971)

Why this record matters
The phrase “mexican composer (1910-1982)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Dec 26, 2025. The linked authority identifier is Q346130. VIAF identifies the subject as 18772986. The Library of Congress control number is n88119786. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1910, 1982, 1935 and 1942.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
