Editing Ternary form (section)

==Ternary form within a ternary form==
In a complex ternary form each section is itself in ternary form in the scheme of {{Nowrap|[(A–B–A)'''(C–D–C)'''(A–B–A)]}} By convention each part is repeated and only on its first rendition: {{Nowrap|[(A–A–B–B–A)'''(C–C–D–D–C)'''(A–B–A)]}} .<ref name="Benward & Saker" /> An example are the Impromptus (Op. 7) by  [[Jan Václav Voříšek|Jan Voříšek]].<ref>"An Analysis of Three Impromptus for Piano Op. 68 by [[Lowell Liebermann]]" by Tomoko Uchino.</ref>

Expanded ternary forms are especially common among [[Romantic music|Romantic-era composers]]; for example, Chopin's [[Polonaises Op. 40 (Chopin)|"Military" Polonaise (Op. 40, No. 1)]] is in the form {{Nowrap|[(A–A–B–A-B–A)'''(C–C–D–C-D–C)'''(A–B–A)]}}, where the A and B sections and C and D sections are repeated as a group, and the original theme returning at the end without repeats.
