Classical Structures

Classical Structures

Definition and Purpose

  • Classical structures refer to the distinct musical forms used predominantly during the classical period (c. 1750-1820).
  • They were designed to bring a level of order, predictability, and balance to the music, while still allowing ample room for creativity.

Main Types of Classical Structures

  • Sonata Form: This structure consists of three main sections; the exposition, development, and recapitulation. It is often used in the first and sometimes last movement of a work.
  • Minuet and Trio: Based on a very popular dance of the time, this structure is usually found in the third movement of a classical symphony or string quartet.
  • Rondo Form: Characterised by a recurring theme (the ‘Rondo’ theme) that alternates with contrasting sections. This form is often used in final movements.
  • Theme and Variations: In this structure, a theme is followed by variations on that theme. Each variation changes some elements of the theme but retains others, offering a balance of novelty and familiarity.

Use of Classical Structures in Concertos

  • Classical concertos typically consist of three movements that mirror sonata form: fast-slow-fast.
  • The first movement often follows sonata form with an additional feature, the double exposition.
  • The second movement is generally slower and might be set in theme and variations form. It often contrasts with the outer movements, providing a moment of calm.
  • The third movement might utilise either sonata or rondo form, providing a lively and robust conclusion to the concerto.

Influence on the Concerto

  • The concerto format has greatly evolved over time due to classical structures, allowing for greater interplay between the solo instrument and orchestra, rather than simple alternation.
  • The clear definition of form in the classical period helps to distil the conflict and conversation in a concerto between the soloist and the accompaniment.
  • The use of classical structures helps in creating works of greater complexity and depth, enhancing the soloist’s ability to express different facets of musical artistry.
  • Composers like Mozart and Beethoven have used these classical structures in their concertos, demonstrating expressive melody, dynamic contrast, clear structure, and dramatic interplay.
  • Understanding these structures and their historical context greatly assists in appreciating and interpreting classical concertos.
