The pioneer representatives of these two opposing schools were, respectively, Olympus, already familiar to us, and Terpander, both of whom belong to the seventh century B. C. Concerning Olympus’ art a startling assertion is found in Plutarch. He was regarded by Greek musicians as the originator of the enharmonic genus. Upon clearer examination, it has been found that this use of the word 'enharmonic’ does not coincide with the sense in which it is used above, where we explained the three _genera_ of tetrachords. The quarter-tone division is, indeed, a much later product and does not seem ever to have attained to great popularity. The enharmonic scale of Olympus simply consisted of the diatonic _with a step omitted_, so as to avoid all semi-tone intervals in the melodies. This elided tone was probably the Lichanos of the Phrygian scale ([Greek: harmonia]), or f, if we take the octave from d to d´ on the white keys of the piano. The Phrygian was naturally the scale used by Olympus, whose home was Phrygia, but he is also said to have introduced this 'enharmonic’ type of melody into the Dorian mode. When the full octachord came into consideration (originally the scale was limited to seven notes) the omission of the upper tone of the higher semi-tone interval (from b to c) followed as a matter of course. Thus Terpander’s 'enharmonic’ scale is seen to be simply a sort of pentatonic system, the antiquity of which is already evident from our examination of primitive music. Little is known of Olympus’ life. What part of Greece he inhabited we are not told. It seems certain that he practised his art in the service of Apollo. About one hundred years before the beginning of the Pythic games at Delphi he composed a song describing the fight of Apollo with the dragon, which afterward became known as the _Nomos Pythicos_, and which, as we have seen, was regularly performed upon the first day of the Pythic festivals.[39] Of Terpander, however, the first of the _kitharœdic_ nome writers, we have many isolated details, both of legend and fact. There is a story that the lyre of Orpheus was carried on the waves of the sea from the Thracian coast to Antissa on Lesbos, where Terpander was born. Orpheus is, indeed, the singer whom Terpander was said to emulate, while Olympus was supposed to follow the models of Homer. Terpander was the first victor in the Spartan _Carneata_ (festival in honor of Apollo), which began during the twenty-sixth Olympiad. This indicates his settling in Sparta, which is further confirmed by Plutarch, who in his _De musica_ calls him the chief representative of the first period in which Sparta flourished musically. Plutarch also records the legend that he successfully subdued a revolt of the Lacedemonians by the power of his music. To us the most important item of Terpander’s achievements is the addition of the eighth string to the lyre (_kithara_), thus completing the octave.
