Stochastic music is a form of composition that uses random processes to create musical works. It often involves mathematical algorithms and probability to determine elements like pitch, rhythm, and dynamics. This approach allows for a wide range of possibilities, making each performance unique. The term was popularized by composer Iannis Xenakis, who applied concepts from probability theory and statistical mechanics to music. Stochastic music can be seen as a way to explore the relationship between order and chaos, offering composers a new tool for creativity and expression.
