Contains scores and parts housed in the Performance Library, including chamber music, music for orchestra, and band and choir music, to support the performing ensemble credit courses given at the Schulich School of Music of McGill University.

The Gertrude Whitley Performance Library holds more than 5,000 titles of scores and parts for ensembles of 3 players or more and over 1,000 jazz charts. The collection reflects the ensemble credit courses given here at the Schulich School of Music, i.e. orchestra, baroque orchestra, wind symphony, choir, jazz orchestra, contemporary music ensemble, percussion ensemble, brass choir, and various smaller chamber ensembles such as string quartets, woodwind quintets, brass quintets, etc. In addition, the Library houses the Carl Friberg Collection (band music) and part of the Bruce Bower Gift Collection (bassoon music). However, there is no solo or duet music. In fall 2005, the Library was named the Gertrude Whitley Performance Library, in recognition of the generous philanthropic gift from the Whitley Foundation in the creation of the new facilities for the Performance Library in the new music building.
