Klact-Oveeseds-Tene is a bebop composition by Charlie Parker, a contrafact based on the chord changes of Juan Tizol's "Perdido." It was recorded on November 4, 1947, at WOR Studios in New York by the Charlie Parker Quintet featuring Miles Davis on trumpet, Duke Jordan on piano, Tommy Potter on bass, and Max Roach on drums, and released on Dial Records in 1949. The tune carries one of the most enigmatic titles in jazz. According to jazz historian Ken Vail's research, when producer Ross Russell pressed Parker for a title during the session, Parker simply wrote the name on the back of a Three Deuces nightclub minimum-charge card without explanation. The mystery was later unraveled through the observation of Parker's colleague Red Rodney, who noted that Bird was "dabbling with German." Linguistic analysis revealed the title to be Parker's onomatopoetic rendering of the German phrase "Klatschen - Auf Wiedersehen!" meaning "Clapping - See you!" -- the sound of applause and a casual goodbye transformed into bebop nomenclature. The title has appeared in variant spellings across releases, including Klact-Oveereds-Tene and Klactoveedsedstene. While not as widely covered as Parker standards like Ornithology or Confirmation, the tune has been revisited by later musicians including Roy Hargrove, Christian McBride, and Stephen Scott, and appears on the 2004 compilation Birdsong.
