Electro-acoustic refers to a type of sound production that combines electronic and acoustic elements. This approach often involves using microphones, speakers, and electronic effects to enhance or manipulate sounds produced by traditional acoustic instruments, such as guitars or pianos. In electro-acoustic music, composers and performers explore the interaction between live sound and electronic processing. This genre can include various styles, from experimental to popular music, and is often used in concerts, installations, and recordings to create unique auditory experiences.
