Six Marimbas by Steve Reich
Have a listen to this amazing piece of music by Steve Reich (a living composer from USA) that uses lots of repetition. It shows a style of modern music that is called MINIMALISM. It uses a few different ideas and repeats. The patterns overlap and create layers which pull you into the music (comments from 5i)
You may also like to see some artwork by a living British artist called Bridget Riley. She uses similar ideas using minimal ideas in her art.
