Salvatore Giovanni Martirano (January 12, 1927 – November 17, 1995) was an American composer of contemporary classical music. Born in Yonkers, New York, he taught for many years at the University of Illinois. He also worked in electronic music and invented electronic musical instruments.
Many of Martirano's early works incorporate twelve-tone compositional techniques as well as jazz, vernacular, and multimedia idioms. His best-known composition, "L's GA" (Lincoln's Gettysburg Address), was widely performed in the late 1960s and early 1970s. It became associated with the anti-Vietnam War movement.
In 1969, Salvatore Martirano, along with a group of engineers and musicians at the University of Illinois, began work on the design and construction of a musical electronic instrument. The instrument, named the SAL-MAR Construction, is a hybrid system in which TTL logical circuits (small and medium scale integration) drive analog modules, such as voltage-controlled oscillators, amplifiers and filters.
I'm not certain what "art music" is. Perhaps there's only music.
