Leitmotif

A leitmotif or leitmotiv /ˌlaɪtmoʊˈtiːf/ is a "short, constantly recurring musical phrase" associated with a particular person, place, or idea. It is closely related to the musical concepts of idée fixe or motto-theme. The spelling leitmotif is an anglicization of the German (IPA: [ˈlaɪtmoˌtiːf]), literally meaning "leading motif", or perhaps more accurately, "guiding motif". A musical motif has been defined as a "short musical idea ... melodic, harmonic, or rhythmic, or all three", a salient recurring figure, musical fragment or succession of notes that has some special importance in or is characteristic of a composition: "the smallest structural unit possessing thematic identity."

In particular, such a motif should be "clearly identified so as to retain its identity if modified on subsequent appearances" whether such modification be in terms of rhythm, harmony, orchestration or accompaniment. It may also be "combined with other leitmotifs to suggest a new dramatic condition" or development. The technique is notably associated with the operas of Richard Wagner, and most especially his Der Ring des Nibelungen, although he was not its originator and did not employ the word in connection with his work.
