Model 51 Fox Renard Intermediate Bassoon: Originally introduced in 1965, the Renard Model 51 bassoon's long bore design can be identified by its very warm "round" tone, with even balance and excellent intonation throughout the entire range. Like the Model 41, this instrument has a durable body and secure acoustical design. In addition, this model features a compact key mechanism that makes it a popular choice for middle school music programs, those starting on bassoon at a young age, and beginning players with smaller hands.
