Pythagoras, a Greek philosopher and mathematician, recommended singing and playing a musical instrument every day to eliminate fear, worry and anger from the body.
Founder of the Pythagoreans, established in Crotona around 520 BC, his discoveries in mathematics, astronomy and music were famous. He considered the number as the true structure of things and as the basis of the harmony of the spheres.
For the Pythagoreans, both music and the soul share a number base. The Pythagoreans, when they went to sleep, purified their reasoning ability from the disturbances and noises to which they had been exposed during the day, by means of certain peculiar odes and songs. In this way they tried to sleep soundly, and have few good dreams. When they got up, they were freed again from the torpor and heaviness of sleep with the help of songs of another kind.
