The music of ancient Greece was inseparable from poetry and dancing. It was entirely monodic, there being no harmony as the term is commonly understood. The earliest music is virtually unknown, but in the Homeric era a national musical culture existed that was looked upon by later generations as a “golden age.” The chief instrument was the phorminx, a lyre used to accompany poet-singers who composed melodies from nomoi, short traditional phrases that were repeated. The earliest known musician was Terpander of Lesbos (7th cent. B.C.). The lyric art of Archilochus, Sappho, and Anacreon was also musical in nature.
In the 6th cent. B.C., choral music was used in the drama, for which Pindar developed the classical ode. The main instruments at this time were the aulos, a type of oboe associated with the cult of Dionysus, and the kithara, a type of lyre associated with Apollo and restricted to religious and hymnic use. This classical style of composition decayed in the last quarter of the 5th cent. B.C.
