Variation forms include ground bass, passacaglia, chaconne, and theme-and-variations. [7] Ground bass, passacaglia and chaconne are typically based on brief ostinato motifs providing a repetitive harmonic basis and are also typically continuous evolving structures.
A basic theme is reprised throughout a musical work, but it undergoes constant transformations and disguises and is made to appear in several contrasting roles. However, the transformations of this theme will always serve the purpose of "unity within variety" that was the architectural role of sonata form in the classical symphony.
The double variation (also known as alternating variations) is a musical form used in classical music.It is a type of theme and variations that employs two themes. In a double variation set, a first theme (to be called A here) is followed by a second theme (B), followed by a variation on A, then a variation on B, and so on with alternating A and B variations.

In music, form refers to the structure of a musical composition or performance.In his book, Worlds of Music, Jeff Todd Titon suggests that a number of organizational elements may determine the formal structure of a piece of music, such as "the arrangement of musical units of rhythm, melody, and/or harmony that show repetition or variation, the arrangement of the instruments (as in the order of ...
However, Schoenberg and other theorists who used his ideas as a point of departure see the theme and variations as having an underlying role in the construction of formal music, calling the process continuing variation, and argue from this idea that the sonata-allegro form is a means of structuring the continuing variation process.
Theme and variations form starts with a theme, followed by multiple variations. This theme is usually eight to thirty-two bars in length, and may be constructed as a musical sentence, period, or small ternary. Each variation is a recurrence of the theme with melodic, harmonic, rhythmic and ornamental changes. Theme and variations sometimes ...
The simplest kind of sonata rondo form is a sonata form that repeats the opening material in the tonic at the end of the exposition and recapitulation sections. [A B' A] exp [C"] dev [A B A] recap. By adding in these extra appearances of A, the form reads off as AB'AC"ABA, hence the alternation of A with "other" material that characterizes the ...
