Acousmatic music is a genre of sound art that focuses on recorded sounds played back through speakers, rather than live performances. The term originates from the Greek word "akousma," meaning "that which is heard." This type of music emphasizes the auditory experience, allowing listeners to engage with sounds in a way that can evoke emotions and imagery without visual context. In acousmatic music, the source of the sounds is often hidden, creating a sense of mystery and encouraging listeners to interpret the audio in their own way. Composers like Pierre Schaeffer and Luc Ferrari have been influential in developing this form, exploring the relationship between sound and perception.
