Aleatoric music is a type of music that is created through chance or randomness. It is often referred to as "chance music" or "indeterminate music". However, there are several other synonymous words that can be used to describe or refer to aleatoric music. For example, "aleatory music" is a commonly used term, as well as "random music" and "non-deterministic music". Other lesser-known synonyms include "stochastic music", "chaos music" and "probability music". While the terminology may vary, the concept remains the same - music that is created or performed through an element of chance or unpredictability.
