The suite is made up of many successive movements. It originates from pair dances, developing and evolving during different periods. Standard classic suites consist mainly of traditional dances such as the allemande, courante, sarabande and gigue. This paper closely examines three suites¡GPartita in B-flat major No.1 Bwv 825 by J. S. Bach, Suite Bergamasque by Debussy and Suite op.25 by Schönberg. At first, focus is on the definition, origin, development and changes of the genre, and then the features of dances in each of the three suites will be fully discussed, especially in the ones by J. S. Bach and Schönberg. J. S. Bach was one of the greatest composers of suites in the Baroque period. In his works, traditional dances are highly stylized, full of characteristics, as observed in his Partita in B-flat major No.1 Bwv 825. However, the form gradually declined after the Baroque period; until the Romantic period, when the character pieces rise, usually forming a group, which correspond to the nature of the suites. In the Twentieth century, influenced by Neoclassicism, Schönberg composed Suite op.25, which adopts the form of the suite, imitating the style of the traditional dances, while utilizing his twelve-tone technique for the very first time¡I To sum up, drastic changes can not be detected in the styles of dances from different periods. It is the distinctive characteristics of different composers that bring about the diversities.
