Abstract
Euterpea is a computer music library written in Haskell. As such it is not a new language, although it has the "look and feel" of a special-purpose language. Euterpea is being developed in the context of Yale's new C2 Initiative (Creative Consilience of Computing and Arts), and is the only computer music programming environment based on a purely functional programming model.

In this talk we discuss the design rationale for Euterpea, describe its basic functionality, and highlight some of its more innovative features: a vertical language design (from signals to symphonies), a separation between structure and interpretation (form and function), a musical user interface (MUI), real-time sound synthesis, and its use of functional reactive programming (FRP) in interactive music applications.
