Located at the rear of the school, it is the building where the music department is based. There is a music library in the basement as well as a dozen or so music practice rooms, each having a piano, used for private lessons. It contains a keyboard suite allowing first and second years to learn basic keyboard playing and a hall on the west side used primarily for orchestra rehearsals. The original part of the building where the practice rooms are now located had been used in the 1950s and '60s as a bicycle shed.
