Aleatory techniques

Definition

Aleatory techniques refer to compositional methods that incorporate elements of chance or randomness into the music-making process. These techniques can involve leaving aspects of the composition open to interpretation by performers, resulting in a unique realization of the piece each time it is played. This approach allows for spontaneity and unpredictability, challenging traditional notions of authorship and structure in music.
