v. Allegro Agitato
Couper’s score for Xanadu includes names of percussion instruments (side drum, cymbals, Chinese gongs, and wood blocks) for use as incidental music during the play. These were evidently used during the several processions and dockyard scenes. The two-piano music is notated and called a “ballet,” presumably as an overture or entr’acte for costumed dancers (there being no call for a ballet during the action of the play). While the music may not be overtly programmatic, it may relate loosely to the Samuel Taylor Coleridge opium-inspired poem of the same name:
“In Xanadu did Kubla Kahn a stately pleasure dome decree…
the sacred river ran… a savage place!… woman wailing for her demon-lover… a mighty fountain… these dancing rocks… meandering with a mazy motion… ancestral voices prophesying war!”
Musically one can see traces of Stravinsky’s Russian folk melodies as found in Pulcinella or Les Noces, pentatonic lines surrounded by dense clusters (as often found in Henry Cowell’s piano music of the time), the muddy dissonance of parts of Charles Ives’s Three Quarter Tone Pieces, and perhaps even some of George Antheil’s futuristic motor rhythms as found in his Ballet Mécanique (which she may have seen in New York in 1926). In this first of her quarter-tone works she favors the use of both pianos at the same time, creating dissonant clouds of sound, rather than the alternating, melodically tortuous ultra-chromaticism as found in the Dirge a few years
Xanadu was subsequently performed on May 15, 1932 at the YWCA in San Francisco, by the composer and Malcolm Thurburn, at one of Henry Cowell’s New Music Society concerts. The work was rather overshadowed by the other event of the program, the demonstration of his and Leon Theremin’s Rhythmicon, an instrument designed to extend the pitch ratios of the overtone series to durational cycles too.
