The Mormon Youth Symphony and Chorus (MYSC) was an official musical organization of the Church of Jesus Christ of Latter-day Saints (LDS Church) from 1969 to 1999, composed of young musicians aged 18 to 33. In its 30-year history, MYSC was credited with many television specials, numerous recordings, concerts, and several major tours throughout the United States. The group was disbanded during the 1999 reorganization of the Tabernacle Choir and resulting creation of the Orchestra at Temple Square. The choral arm of the group provided music for the church's annual and semi-annual general conferences, usually during the Saturday morning sessions.
