Harmony (from the Greek ἁρμονία “union” “proportion” “harmony”) is when different elements work together and bring pleasure. In this piece Daniele pays homage to the Greek philosopher Pythagoras, who has devoted a substantial part of his work to the fate of mankind and its soul. To live a life of interior harmony and in perfect balance is, in the philosopher’s eyes, the foundation of happiness. Key of Pythagoras’ philosophical thought, harmony is the ability of talking and conversing as if to dance.
