The Sonata Form in Music: A Beginner's Guide

Classical music theory is based on the sonata form. The classical sonata form has directed the composition of many symphonies, concertos, and string quartets, in addition to its well-known application in piano sonatas.

What Is Sonata Form and How Does It Work?

The sonata form is a three-part musical structure in which each section explores a common topic or motif. While the term "sonata" has had a variety of meanings throughout music history, the term "sonata form" refers to a manner of arranging a movement within an instrumental composition.

Sonata Form is divided into three sections.

Exposition, development, and recapitulation are the three main sections of the sonata form.

• The composer puts out the piece's main melodic elements in the first subject group during the exposition of a sonata. These themes are first played in the piece's tonic key. (The main themes of a sonata written in C major would be articulated first in C major.) The exposition part then shifts gears. It modulates to the dominant key if the composition is in a major key (in C major, this would be the key of G major). The first modulation in a sonata written in a minor key is to the relative major (in C minor, the first modulation is to E major). The first and second themes then appear in a variety of new keys (in the key of C major, this might involve slightly more distant keys like D major or E minor). Finally, the exposition comes to a close with a codetta.
• Thematic material from the first section cycles through different keys with varied modifications in the development section, usually starting with the key from the end of the exposition. The development section in eighteenth-century Baroque and Classical sonatas is relatively brief. Long explorations and numerous new musical concepts can be found in the development portion of Romantic-era music, which dominated the nineteenth century. (Compare the developing part of Beethoven's Symphony No. 3 Eroica with the opening movement of Mozart's Symphony No. 40 to see this in action.) Traditional progressions culminate with a re-transition, in which the music hangs for a while on a dominant seventh chord to prepare the ear for a return to the home key.
• Recapitulation: The music returns to the primary themes of the exposition part in this concluding sonata-form movement. It also has a brief transition section, which is frequently referred to as a secondary development. The motifs eventually come to a flawless authentic cadence in the home tonality.

A sonata's three movements are sometimes preceded by an overture and followed by a coda section.

A Quick History of Sonatas Form sonatas first appeared in the early eighteenth century and gained popularity during the Classical and Romantic periods.

• The word "sonata" has its origins in the seventeenth-century Baroque period. It is made out of the words "cantata," which refers to vocal music, and "sonare," which refers to instrumental music. Pergolesi's Trio Sonata No. 3 in G Major, written shortly before the composer's death in 1736, is a notable early example of the sonata form in action.
• Popularity during the Classical Period: Composers from the Classical period, including as Franz Joseph Haydn and Wolfgang Amadeus Mozart, later adopted the form, emphasising its obvious order and structure in their multi-movement pieces.
• Sonatas became a popular blueprint for the first movement of a symphony after their incorporation into symphonies. This musical style, known as sonata-allegro form, introduces the main themes of a symphony before giving place to a significantly different second movement. (Traditionally, Classical and Romantic symphonies start with a lively allegro movement, while the second movement is known as the "slow movement.")
• Sonata form can be incorporated into other musical genres, such as string quartets and instrumental concertos from the Classical and Romantic periods. The sonata form can also be combined with other musical forms such as the minuet (an A-B-A binary form) and the rondo (which is usually structured A-B-A-C-A-D). In the Classical period, the sonata rondo form was a very popular musical structure.
• The most rigidly ordered sonatas tend to originate from the Classical period, which spanned around 1750 to 1820. The sonata form began to break from established norms as music became more brazenly experimental in the nineteenth-century Romantic era and the twentieth-century Modern era.

Classical Sonatas: 7 Examples

Immersing oneself in playing a sonata is one of the finest methods to grasp the musical structure of the sonata. The following piano sonatas are suitable for pianists who have learned the fundamentals of the instrument.

• Sonata in G Major Hob XVI:8 by Franz Joseph Haydn
• Sonata in F major Hob. XVI:9 by Franz Joseph Haydn
• Sonatina Op. 36 No. 1 by Muzio Clementi
• Sonatina Op. 49 by Ludwig van Beethoven
• Sonata No. 14 ("Moonlight") by Ludwig van Beethoven
• Sonata in C Major K 545 ("Sonata Facile") by Wolfgang Amadeus Mozart
• Sonata in G Major K 283 by Wolfgang Amadeus Mozart
