Carnivalicante

A leitmotif is a musical term referring to a recurring theme, associated with a particular person, place, or idea. In particular such a theme 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.
Although usually a short melody, it can also be a chord progression or even a simple rhythm. Leitmotifs can help to bind a work together into a coherent whole, and also enable the composer to relate a story without the use of words, or to add an extra level to an already present story.
