This article is about the musical form. For the cyclic isomers of monosaccharides, see Monosaccharide#Structure and nomenclature.

Cyclic form is a technique of musical construction, involving multiple sections or movements, in which a theme, melody, or thematic material occurs in more than one movement as a unifying device. Sometimes a theme may occur at the beginning and end (for example, in Mendelssohn's A minor String Quartet or Brahms's Symphony No. 3); other times a theme occurs in a different guise in every part (e.g. Berlioz, Symphonie Fantastique, and Saint-Saëns's 'Organ' Symphony.
