What is the difference between chance music and minimalist music?

Chance music, also known as aleatoric music, involves elements of unpredictability and randomness in its composition or performance, allowing performers to make decisions that affect the outcome. In contrast, minimalist music is characterized by repetitive structures, gradual changes, and a focus on tonal harmony, often creating a meditative or trance-like effect. While chance music embraces uncertainty, minimalist music relies on deliberate patterns and simplicity to evoke specific emotional responses.
