Ornette Coleman, Charlie Parker and Thelonious Monk. In The Crying of Lot 49, the lead singer of The Paranoids sports "a Beatle haircut" and sings with an English accent. In the closing pages of Gravity's Rainbow, there is an apocryphal report that Tyrone Slothrop, the novel's protagonist, played kazoo and harmonica as a guest musician on a record released by The Fool in the 1960s (having magically recovered the latter instrument, his "harp", in a German stream in 1945, after losing it down the toilet in 1939 at the Roseland Ballroom in Roxbury, Boston, to the strains of the jazz standard "Cherokee", upon which tune Charlie Parker was simultaneously inventing bebop in New York, as Pynchon describes). In Vineland, both Zoyd Wheeler and Isaiah Two Four are also musicians: Zoyd played keyboards in a '60s surf band called The Corvairs, while Isaiah played in a punk band called Billy Barf and the Vomitones. In Mason & Dixon, one of the characters plays on the "Clavier" the varsity drinking song that will later become "The Star-Spangled Banner"; while in another episode a character remarks tangentially "Sometimes, it's hard to be a woman". In his introduction to Slow Learner, Pynchon acknowledges a debt to the anarchic bandleader Spike Jones, and in 1994, he penned a 3000-word set of liner notes for the album Spiked!, a collection of Jones's recordings released on the short-lived BMG Catalyst label. Pynchon also wrote the liner notes for Nobody's Cool, the second album of indie rock band Lotion, in which he states that "rock and roll remains one of the last honorable callings, and a working band is a miracle of everyday life. Which is basically what these guys do". He is also known to be a fan of Roky Erickson. Investigations and digressions into the realms of human sexuality, psychology, sociology, mathematics, science, and technology recur throughout Pynchon's works. One of his earliest short stories, "Low-lands" (1960), features a meditation on Heisenberg's uncertainty principle as a metaphor for telling stories about one's own experiences. His next published work, "Entropy" (1960), introduced the concept which was to become synonymous with Pynchon's name (though Pynchon later admitted the "shallowness of [his] understanding" of the subject, and noted that choosing an abstract concept first and trying to construct a narrative based on it was "a lousy way to go about writing a story"). Another early story, "Under the Rose"
