Rondo • Most frequently the final movement of a sonata, string quartet, or symphony • A principle theme alternates with 1 or more contrasting themes • Began to be commonly used in the classical music era • Example: F. Kuhlau – Sonatina Opus 20, No.1 in C Major – Rondo, Allegro • http://www.youtube.com/watch?v=fzRnOa2O0S4
A section comes “round and round” again • Often in the form ABACABA, in which A is the rondo theme • The recurring element is sometimes embellished or shortened for variation
Sonata Allegro • Usually found as the 1st movement of a sonata, string quartet, or symphony • Used widely since the early Classical period • Example: Beethoven – Sonata op.49 no.2 Allegro • http://www.youtube.com/watch?v=ywrv2dKwJ9E
Simplistically put, an ABA’ form • The first A section is called the "Exposition." (has a modulating bridge) • The B section, or "Development" follows the Exposition. It usually uses some material from the Exposition, but in an altered way. • The A' section or "Recapitulation," the A material returns relatively intact.
Binary • Consists of 2 approximately equivalent sections, although they may be of unequal length • Example: J.S. Bach – Minuet in G Major (No.1) • http://www.youtube.com/watch?v=on1DDSLdDOo&feature=related
Main characteristic is 2 related sections of roughly equal duration • Popular in the Baroque period • First section will usually modulate to a related key: usually to the dominant (V) in major keys and the relative major in minor keys • A and B sections are often separated by repeat signs, so often described as AABB form
Can be described as: • Simple or Rounded (ABA’) • Sectional (ends with perfect or authentic cadence in the tonic key) or Continuous (ends with any other cadence) • Symmetrical (A and B are roughly equal in length) or Asymmetrical (A and B are not equal in length)
Minuet and Trio • Often the 3rd movement of the classical sonata cycle • An ABA form (minuet, trio, minuet) in a moderate triple meter • Example: Mozart – Minuet and Trio in G K.1 • http://tw.truveo.com/Wolfgang-Amadeus-MOZART-Minuet-and-Trio-in-G-K1/id/2107661107
Type of ternary design • Minuet (aristocratic dance in ¾ meter) • Strong downbeat • Binary design in which each sub-section is repeated • Trio • Lighter and sweeter than the Minuet • Each sub-section is repeated • Minuet returns • Minuet was a French social dance • Livelier form of the minuet later developed into the scherzo
Theme and Variations • Reiteration with changes • Variations repeat the theme but the theme is changed in some important way • Example: John Thompson – Variations on the Theme Three Blind Mice • http://www.youtube.com/watch?v=wKp_D2aSnN4
Consists of a Theme that is usually made up of four or eight bar phrases • Followed by several Variations in which the theme is elaborated, developed, and transformed. • Usually ends with a Coda
