Thomas Pynchonís interest in music is audibly reflected in the rich intertextual environments of his works such as Gravityís Rainbow, a novel which includes numerous allusions to musical pieces, descriptions of performances, and song lyrics. The latter stand out from prose narrative as they introduce new diegetic dimensions to the novel by offering playful commentary on its plot and characters. The present study examines the novelís acoustic background, pointing to the formal structure of songs and its role in locating singing human voices in opposition to noises emitted by technological devices such as V2 rockets. A classification scheme shows how Pynchonís formal experimentation juxtaposes written and oral variants of language, thus connecting songs to one of the novelís thematic centers ó problematics of order. This function of songs is examined in an episode of Vaslav Tchitcherineís mission of promoting literacy among oral tribes of Kazakhstan, that serves as a commentary on the conventional character of writing systems and their ability to transform the poetic quality of language into a systematic structure.
