The Rivers School is anindependent,coeducationalpreparatory school inWeston, Massachusetts.
Rivers School was founded in 1915 as an educational institution for boys inBrookline, Massachusetts. Robert W. Rivers founded the school and was its first headmaster. The Country Day School for Boys ofBoston merged with Rivers in 1940, and the school moved to its present location inWeston in 1960. It became co-educational in 1989.[2]

The Rivers School Conservatory was founded in 1975 by Ethel Bernard, one of the pioneers of the music school movement. She approached Rivers School with the idea of using the then-unoccupied former headmaster's house on the campus (now called Blackwell House after George H. Blackwell).[3]
It was first called the Music School at Rivers, then Rivers School Conservatory. In 1978, theAnnual Seminar on Contemporary Music for the Young was established,[4] with guests includingJohn Cage (1983). All pieces performed are composed in the 25-years prior to each seminar. Recent examples includeMatinee: The Fantom of the Fair byLibby Larsen.[5][6]
The Conservatory currently has more than 750 students, including a student orchestra program, jazz and chamber ensembles, music theory and composition, a marimba program,[7][8][9] choruses, master classes, workshops, and private lessons for instruments, piano, and voice.[3]
