He joined the Stanford community as a Department of Music professor in 1958. He also co-founded the university's Center for Computer Research in Music and Acoustics, a multi-disciplinary research facility that combines, studies and creates computer technology and music.
A skilled computer programmer, he made many essential contributions to the Center. SCORE, a music notation input program he developed, was the first program of its kind and is considered today's quality standard.
"His vision and his deep knowledge of music notation extended SCORE to computerized music typography, which became, and remains, the benchmark by which all published music is judged," said Professor Emeritus John Chowning, a former graduate student and colleague of Smith's.
Smith was born in Oakland, Calif., in 1925. At 15 years old he began studying music with modernist composer Darius Milhaud. He went on to earn bachelor's and master's degrees from the University of California-Berkeley, where he studied with Roger Sessions, and later attended the Paris Conservatory.
He also served in the U.S. Navy from 1943 to 1946 and began his teaching career after returning. In 1951, he took over Milhaud's courses at Mills College, then at the University of Chicago and finally at Stanford, where he retired in 1992. He performed with New York City Ballet, Chicago Lyric Opera, Chicago Symphony, San Francisco Opera and San Francisco Symphony.
He was married for 65 years to Edith Smith, an artist and teacher who died in 2011. He is survived by his children, Stefanie, Clement and Teresa.
A memorial will be held at the Center for Computer Research in Music and Acoustics at 660 Lomita Drive, Stanford on Saturday, Jan. 18, at 2 p.m.
