The Theoretical System of Ancient Greek Music has been rescued. We can draw information about the instruments that Ancient Greeks used from various sources such as vase paintings, statues, reliefs, mosaics, etc. as well as from writers such as Aristoxenos and Cleonidis. Through these sources we can deduce a lot about Ancient Greeks’ musical education. Many researchers from around the world have attempted to interpret the few play samples that have been rescued but it is true that each and every one of us, using our imagination, we can travel back in time and hear this music in our own way!
Plato, Aristotle and other philosophers move one step further and form the theories of ethics and theories of music ethics that look at the influence of music over the emotions and the mentality of humans. According to music ethics, every rhythmic and melodic move has an emotional countermove. Therefore, music may affect a person in a positive way or in a negative way.
However, ethics do not rely solely on general findings but also in the aesthetic exploration of the structural parameters of music by examining the ethos of melody, harmonies (tropical classifications), genus and rhythms.
