20th century music

The 20th Century saw a revolution in music listening as the radio gained popularity worldwide and new media and technologies were developed to record, capture, reproduce and distribute music. Because music was no longer limited to concerts and clubs, it became possible for music artists to quickly gain fame nationwide and sometimes worldwide. Conversely, audiences were able to be exposed to a wider range of music than ever before. Music performances became increasingly visual with the broadcast and recording of music videos and concerts. Music of all kinds also became increasingly portable. Headphones allowed people sitting next to each other to listen to entirely different performances or share the same performance.
20th Century music brought a new freedom and wide experimentation with new musical styles and forms that challenged the accepted rules of music of earlier periods. The invention of musical amplification and electronic instruments, especially the synthesizer, in the mid-20th century revolutionized popular music and accelerated the development of new forms of music.
