We come now to a lofty form of choral and orchestral music, which we owe to Mendelssohn. In setting two of the Greek tragedies of Sophocles he had no old Greek music for a model. The spirit of the dramas lay in the text of Sophocles. He had read the _Antigone_ in the Greek, and so far got his inspiration at first hand. He took the suggestion from Frederic William IV., King of Prussia, during a summer residence in Berlin in 1841. The peculiar function of the Chorus in the Greek tragedies, as a mediator between the actors and the audience, commenting in some sort of rhythmical chant upon what was passing on the stage, and the sublimity of some of those choruses, make us feel that there could not have been a truer artistic idea than that of setting them to music, realizing and carrying out their vague embryonic musical aspiration as it could only be realized in these modern times after music had become an art. Mendelssohn's inspiration seems to have sprung congenially from that of Sophocles; and this music is of the freshest, manliest, most original and vigorous that he has left. _Antigone_ was the first experiment. He composed it in eleven days:--Overtures, single and double choruses for male voices, with full orchestral accompaniment for all that are lyrical in subject; melodramatic bits, as where Antigone descends into the vault; and chords here and there making expressive background to the spoken verse. The piece was first played on the royal stage at Potsdam; and afterwards on the King's birthday before a select audience, the venerable Tieck presiding. When it was given at Leipsic, a meeting of "learned Thebans" signed an address to Mendelssohn, thanking him "for substantially reviving an interest in the Greek tragedy." The music has since made its mark everywhere, whether given on the stage with action, or only sung and played in concert rooms,--at Athens in the original Greek. Nobler men's choruses are never heard than that rich, sweet, pensive moralizing one which sings of man's wondrous faculties and limitations; or that superb hymn to "Bacchus" (double chorus),--as full of pomp and splendor as the Wedding March,--in which the composer gave free rein to his enthusiasm; or the opening invocation to "Helios." _Oedipus at Colonos_ he composed at Frankfort in 1844, about the time when he began to finish _Elijah_, and write the Violin Concerto and the music to _Athaliah_. A favorite with the men's Choral clubs is the chorus which recounts the beauties of Colonos and the glories of Athens. The music is wonderfully faithful to the ever kindling enthusiasm of the words.
