Relation of music with mathematics

The theorists of Music often use mathematics to get an in depth understanding of music and its working process. Greeks were the first to research and make musical scales equivalent to numerical ratios. The other ancient civilizations like Chinese and Egyptians are known to have studied the mathematical dogma of sound. All of them believed that the nature consisted of sounds that came out of numbers. It is also believed that composition of music can be done in the form of musical applications present in the form of abstract algebra and number theory. Till date many composers make music on such guidelines.
