Music history eras

Ancient music:
The prehistoric era is considered to have ended with the development of writing, and with it, by definition, prehistoric music. "Ancient music" is the name given to the music that followed. The "oldest known song" was written in cuneiform, dating to 4,000 years ago from Ur. It was deciphered by Prof. Anne Draffkorn Kilmer (University of Calif. at Berkeley), and was demonstrated to be composed in harmonies of thirds, like ancient gymel, and also was written using a Pythagorean tuning of the diatonic scale.
Double pipes, such as those used by the ancient Greeks, and ancient bagpipes, as well as a review of ancient drawings on vases and walls, etc., and ancient writings (such as in Aristotle, Problems, Book XIX.12) which described musical techniques of the time, indicate polyphony. One pipe in the aulos pairs (double flutes) likely served as a drone or "keynote," while the other played melodic passages. Instruments, such as the seven holed flute and various types of stringed instruments have been recovered from the Indus valley civilization archaeological sites.
Indian classical music (marga) can be found from the scriptures of the Hindu tradition, the Vedas. Samaveda, one of the four vedas, describes music at length. The history of musical development in Iran (Persian music) dates back to the prehistoric era. The great legendary king, Jamshid, is credited with the invention of music. Music in Iran can be traced back to the days of the Elamite Empire (2,500-644 B.C). Fragmentary documents from various periods of the country's history establish that the ancient Persians possessed an elaborate musical culture. The Sassanid period (A.D. 226-651), in particular, has left us ample evidence pointing to the existence of a lively musical life in Persia. The names of some important musicians such as Barbod, Nakissa and Ramtin, and titles of some of their works have survived.
The term Early music era may also refer to contemporary but traditional or folk music, including Asian music, Persian music, music of India, Jewish music, Greek music, Roman music, the music of Mesopotamia, the music of Egypt, and Muslim music.
