Roaratorio, an Irish circus on Finnegans Wake is a musical composition by American avantâÂÂgarde composer John Cage. It was composed in 1979 for Klaus Schöning of West German Radio and premiered as one of the entries in his radio series. The piece realizes CageâÂÂs indeterminate conceptual score âÂÂ_____, _____ Circus on _____âÂÂ, which provides instructions on translating any book into performance; for Roaratorio, the source text is James JoyceâÂÂs novel Finnegans Wake. Texts from it also appear in CageâÂÂs songs âÂÂThe Wonderful Widow of Eighteen Springsâ (1942) and âÂÂNowth upon Nachtâ (1984). The mesostic text of Roaratorio was published separately as Writing for the second time through Finnegans Wake.
Cage reduced JoyceâÂÂs 626âÂÂpage novel to a 41âÂÂpage mesostic, Writing for the second time through Finnegans Wake, by centreâÂÂcolumn acrostics spelling âÂÂJAMES JOYCEâ (no repeated syllables).
The recorded mesostic recital is interwoven with:
Cage aligned spatial coordinates (page and line) of each Wake reference with temporal markers (minutes and seconds) in his recordingâÂÂfor example, âÂÂJiccupâ (p. 4 l. 11) occurs at 14 seconds into the recital.
Athenäum (Königstein) published the mesostic text in book form in 1982.
