The Marlboro Music School and Festival is a retreat for advanced classical training and musicianship held for seven weeks each summer in Marlboro, Vermont, in the United States. Public performances are held each weekend while the school is in session, with the programs chosen only a week or so in advance from the sixty to eighty works being currently rehearsed. Marlboro Music was conceived as a retreat where young musicians could collaborate and learn alongside master artists in an environment removed from the pressures of performance deadlines or recording. It combines several functions; Alex Ross describes it as functioning "variously as a chamber-music festival, a sort of finishing school for gifted young performers, and a summit for the musical intelligentsia".
