Acoustic music facts for kids
Acoustic music is music which is played by using acoustic musical instruments, i.e. instruments in which the sound is not made louder by electronic amplification. Before electronic musical instruments were created in the 20th century all instruments were acoustic.
Classical music is usually played using only acoustic musical instruments, although some 20th century composers such as Karlheinz Stockhausen used electronic instruments, sometimes together with acoustic instruments.
