Abstract
In his treatise "Elementa harmonica," Aristoxenus of Tarentum formulated a distinctive philosophical framework within the realm of sound exploration, deviating from the harmonics theory advanced by the Pythagoreans. A pivotal disparity lies in the methodological approach to research. Aristoxenus posited meticulous observation of acoustic phenomena as the foundational step in all inquiries, constituting a fundamental criterion for truth. He asserted that perception alone could authenticate the fidelity of the observed state of affairs. Aristoxenus vehemently opposed the Pythagorean disregard for auditory testimony, deeming it a notable methodological lapse. According to him, the harmonikos must serve as a vigilant observer of acoustic phenomena, equipped with a discerning and cultivated musical ear.
