Fugue \Fugue\, n. [F., fr. It. fuga, fr. L. fuga a fleeing,
   flight, akin to fugere to fiee. See {Fugitive}.] (Mus.)
   A polyphonic composition, developed from a given theme or
   themes, according to strict contrapuntal rules. The theme is
   first given out by one voice or part, and then, while that
   pursues its way, it is repeated by another at the interval of
   a fifth or fourth, and so on, until all the parts have
   answered one by one, continuing their several melodies and
   interweaving them in one complex progressive whole, in which
   the theme is often lost and reappears.

         All parts of the scheme are eternally chasing each
         other, like the parts of a fugue.        --Jer. Taylor.
