In the west, ancient Greek music, like its philosophy and mathematics, reached a brilliant height. Although we can't hear Homer sing an epic poem, the contents of the poem tell us that there was already a brilliant chorus and exquisite and elegant instruments. From the sculpture, painting and history at that time, we can know that music is very close to God and is with poetry. A pluckable stringed instrument "Lira" is also called "Qin Shi" because it is specially equipped with singing poems. Music competitions were often held in ancient Greece, and many musicians who were good at singing and playing emerged. The huge stage is also used to perform comprehensive poetry, drama and music genres, including dialogue, solo, chorus and instrumental accompaniment, especially the tragedies of three great writers Aeschylus, Sophocles and euripides.
