The musical history of the Greeks may be divided into two great periods, the historical, and the mythological. The mythological period covers the entire range of traditions and legends, and extends up to the time when the Greeks began to reckon by Olympiads, or periods of four years, the date of the first Olympiad being 776 B.C. From 776 B.C. to 161 A.D. is the historical period.

To the mythological period belong the stories of Orpheus and Eurydice. Perhaps the noblest and most beautiful of all the fairy tales of art, the building of Thebes and Cadmea by Amphion, who by his playing caused the rocks and stones to move spontaneously. The contest between Apollo and Marsyas, the myth of the Sirens, and numberless other stories and traditions with which the Hellenic mind loved to surround, as with many garlands, the art of music.

The poet Homer, provides us with a link between the traditional and historical periods, and in the "Iliad" and the "Odyssey" are to be found both legend and exact information.

Coming to the historical period proper of Greek music, we cannot fail to be impressed with the broadly moral significance which music possessed for the Greeks. Among the Assyrians, it is to be imagined, music was more or less emotional in character. Among the Egyptians, it apparently shared of the nature of an occult philosophy. Among the Israelites, music was primarily an act of worship; and it is, therefore, to the Greeks that the credit of being the first to recognise that music was highly valuable in and educational environment.

Although not yet an independent art, music probably gained very nearly as much as it lost in this respect, by being made an essential part of the literary and dramatic genius of Greece. Thus, the Greek play resembled more an opera than a play, however, with the music strictly subdued in favour of more dramatic interest. Perhaps the simplest way of making clear the musical aspect of the Greek drama would be to say that a Greek play was like an opera of which the composer wrote the libretto and the librettist wrote the music.

Sometimes the Greek dramatist, as in the case of GEschylus, composed the music to his own tragedies. Sophocles also accompanied the performance of one of his plays upon the cithara (an instrument of the harp kind).

Other than fragments of musical work, which it would be difficult to absolutely accept as authentic, there are no musical compositions of the ancient Greeks now known to be in existence. There has been preserved, however, a considerable body of Greek literature upon the subject of music, including the theoretical writings of Aristoxenus (B.C. 300), Euclid (B.C. 277), Nicho-machus (A.D. 60), Alypius (A.D. 115), Bacchius (A.D. 140), Aristides Quintilianus (A.D. no), and others.

Of these Aristoxenus wrote upon the Elements of Harmonics, Euclid wrote an Introduction, to Harmonics, Nichomachus an Introduction to Harmony, Alypius a work on musical notation, Bacchius, supposed to have been tutor to the Emperor Antoninus, was the author of a short Introduction to Music, in dialogue form. Aristides Quintilianus wrote a treatise, "De Musica," in three books.

These writers, and others, have perpetuated the theoretical systems of the Greeks. Although they give us little or no hint of the practical application of the same, and it is upon their works that the earliest theorists of Europe based their further efforts towards the construction of a musical system at once logical, scientific, and capable of allowing the emotional side of man's musical nature free play.
