The pukl, commonly called dudy, is a bellow-blown bagpipe whose origin and development can be traced to older forms known as grosser Bock and polnischer Bock. The instrument is an important feature in the identity of Chodsko, an ethonographic region of West Bohemia. This thesis shows the significance of the pukl in Chodish tradition through its organology, pedagogy, performance practice, and history. Through the novel Psohlavci, Alois Jirásek offered a footing for reinforcement of Chodish traditions. The thesis argues that a succession of makers, performers, teachers, institutions, and events have woven a web of tradition in which the pukl holds a significant position. Supporting evidence is shown from artworks that are visible to the public as well as decoration on the instrument. Selected from the Chodish canon, the beloved song, ‘Zelený hájové’, illustrates the use of the dialect and ornamentation as being indicative of the region. Two DVDs, The Call of Dudy and Zelený Hájové …, and a glossary of Chodish terms together with a catalogue of field recordings are included.
