Aristoxenus was born in 375 bc in Tarentum, a Greek city in southern Italy and belonged to the group of philosophers called Peripatetics.
He is considered currently the most relevant music´s theorist in the classical world due to his empirical approach given in his work called Elementa harmonica where he vastly wrote about equal-tempered tuning and major-minor tonality and how these are related to the human soul as harmony and how they needed to be evaluated as a sole system by ear voiding cosmology and ethics. He seemed to follow Pythagorean theory
