Minimalist music is a genre that emerged in the mid-20th century, characterized by its simplicity and repetitive structures. Composers often use limited musical materials, such as short motifs or phrases, which are repeated and gradually transformed over time. This approach creates a meditative and immersive listening experience. Key figures in minimalist music include composers like Steve Reich, Philip Glass, and Terry Riley. Their works often feature steady rhythms and harmonies, allowing listeners to focus on subtle changes and textures. This style has influenced various genres, including ambient music and post-minimalism, expanding its reach beyond classical music.
