The theme and variation form may be classified into two groups: sectional variations and continuous variations. Sectional variations are those based on a theme that consists of one or more periods of music, each period clearly divided by a double bar line or caesura. Continuous variations are those based on a theme comprising only a phrase or two, whereby variations are introduced without interruptions such as rests, pauses, etc. | The theme and variation form may be classified into two groups: sectional variations and continuous variations.
