This course offers an in-depth study of individual orchestral instruments, in both their standard practices and extended techniques. We will discuss their uses in solo and chamber ensemble settings in each of the various orchestral choirs, and in the orchestra as a whole. Through original compositions and arrangements, students will learn by emulating representative scores spanning various eras and styles, with the goal of adapting this knowledge to suit their own particular voices. Performers will be invited periodically to demonstrate on their instruments and read through student compositions. As a final project, the Sarah Lawrence Orchestra will do a reading session of student orchestrations.
