The Elody music composition environment proposes lambda-abstraction on musical structures as a fundamental mechanism to represent user-defined musical concepts and compositional processes. The user can define new musical concepts either on top of concrete musical objects by generalizing them via an abstraction operation, or by composing and transforming previously defined abstractions. As the paper will show through several examples, this approach leads to a quite natural formalization as well as a convenient active notation for many musical notions and compositional techniques.
