Experimental sound refers to a genre of music and audio art that explores unconventional techniques and structures. It often incorporates non-traditional instruments, found sounds, and electronic manipulation to create unique auditory experiences. Artists in this field challenge the norms of melody, rhythm, and harmony, inviting listeners to engage with sound in new ways. This genre can include elements from various styles, such as avant-garde, noise music, and musique concrète. Pioneers like John Cage and Karlheinz Stockhausen have significantly influenced experimental sound, pushing the boundaries of what music can be. The focus is often on the process of sound creation rather than the final product.
