Ternary form

A compositional form which consists of three major sections, an A section which states the thematic material, a B section which presents a contrasting theme, and a final A section which restates the opening thematic material. Also, any three part form. Is a tripartite musical structure, three-part song-form, in which the third part is an exact or modified repetition of the first. Standard examples of ternary form can be heard in the minuet and trio movements of Haydn and Mozart.
