Leitmotif

Short, constantly recurring musical phrase

A leitmotif or Leitmotiv is a "short, 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 a partial anglicization of the German Leitmotiv, literally meaning "leading motif", or "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".
