Sonata

Lore & Background

In the Baroque period, a sonata was for one or more instruments, almost always with continuo. Two broad classes were established in the works of Arcangelo Corelli and his contemporaries: the sonata da chiesa (suitable for church) and the sonata da camera (proper for court). The sonata da chiesa normally consisted of a slow introduction, a loosely fugued allegro, a cantabile slow movement, and a lively finale. The sonata da camera consisted almost entirely of idealized dance-tunes. Corelli's Opp. 1–4, which include both sonate da chiesa and sonate da camera, were foundational to the development of the trio sonata and inspired Bach, Vivaldi, Handel, and Telemann. The sonata began to become a separate entity in the 17th to 18th centuries as the canzona became less popular and the suite, concerto, and sonata developed in different directions. Most of these are in one binary-form movement. Both the solo and trio sonatas of Vivaldi show parallels with his concerti. The sonatas of Domenico Paradies are mild and elongated works with a graceful second movement. In the Classical period, the term sonata moved from being one of many terms indicating genres to designating the fundamental form of organization for large-scale works. The usage of sonata as the standard term for multimovement works began in the 1770s. The term was increasingly applied to works for keyboard alone or for keyboard and one other instrument. The most common layout of movements was Allegro, a slow middle movement, and a closing movement often a Rondo or Minuet. Two-movement and four-movement layouts also occurred.

The sonata's significance lies in its evolution from a vague term in the 17th century to a fundamental principle of composing large-scale works by the early 19th century. It was regarded alongside the fugue as one of two fundamental methods of organizing, interpreting, and analyzing concert music. The sonata form influenced most instrumental genres. Though the musical style of sonatas has changed since the Classical era, most 20th- and 21st-century sonatas maintain the overarching structure. The term sonatina is used for a short or technically easy sonata. The sonata's development was shaped by composers such as Corelli, whose trio sonatas were foundational, and later by Haydn and Mozart, who standardized the three-movement layout. The sonata also overlapped with the suite and partita in certain geographical and instrumental contexts, particularly in Germany and for solo keyboard repertoire. The sonata da chiesa and sonata da camera established two broad classes that persisted as a tradition of Italian violin music. The sonata's legacy includes its application to works for solo instruments, keyboard with accompaniment, and other combinations, making it a versatile and enduring form in Western classical music.

• The term sonatina is the diminutive form of sonata, often used for a short or technically easy sonata.
• Corelli's Opp. 1–4, which include both sonate da chiesa and sonate da camera, were foundational to the development of the trio sonata and inspired Bach, Vivaldi, Handel, and Telemann.
• In the Classical period, the term sonata was increasingly applied to works for keyboard alone or for keyboard and one other instrument, such as violin or cello.

From Ambiguity to Architectural Principle

The term sonata did not arrive fully formed. In the 17th century it was entangled with other genres—the sinfonia, the canzona, the concerto—making it an ambiguous label rather than a distinct form. Sinfonias, played by multiple instruments and following the imitative style of the canzona, actually foreshadowed what would become the introductory movement of sonata form. As newer types of canzonas and concertos emerged under the banner of stile moderno, early sonatas absorbed characteristics from all of these, resisting clear definition. The genre finally crystallized between the 17th and 18th centuries, as the canzona lost popularity and the suite, concerto, and sonata each developed along separate trajectories. By the early 19th century, sonata had transcended its original meaning to represent a fundamental principle for composing large-scale works, applied across most instrumental genres and regarded—alongside the fugue—as one of two essential methods for organizing, interpreting, and analyzing concert music.

Corelli's Blueprint and the Baroque Sonata

Arcangelo Corelli's twelve trio sonatas, Op. His work helped establish the sonata da chiesa—a form suited to church use—typically scored for one or two violins with basso continuo. The standard pattern he helped codify included a slow introduction, a loosely fugued allegro, a cantabile slow movement, and a lively finale in binary form that echoed dance-tunes. Corelli's prolific output inspired Bach, Vivaldi, Handel, and Telemann.

Scoring, Overlap, and the Keyboard Question

The instrumentation of the sonata shifted dramatically across eras. In the Baroque period, sonatas almost always featured one or more instruments with continuo. After the Baroque, the norm became a solo instrument—most often a keyboard—or a solo instrument accompanied by keyboard, though sonatas for other solo instruments and other combinations were also composed. A fascinating overlap existed between the sonata and the partita, particularly in Germany's solo keyboard repertoire. As scholar Beste notes, the partita denoted a multi-movement instrumental cycle of dances, overlapping with the sonata only in that specific instrumental and geographical context. Bach's unaccompanied violin sonatas, for instance, conform to Corelli's four-movement church sonata pattern, while his partitas borrow their name from the keyboard tradition as dance cycles. In France, Germany, and England, the sonata and suite experienced overlap, but in Italy they remained distinct because their scoring criteria differed. A suite is built from complete dance movements, whereas a sonata may incorporate dance-derived passages without reaching the formal completeness of a suite.

Enduring Structure and the Diminutive Form

Though the musical style of sonatas has evolved considerably since the Classical era, most 20th- and 21st-century sonatas maintain the overarching structural framework established centuries earlier. This persistence underscores the sonata's role not merely as a historical genre but as a living compositional principle. The term itself remains deliberately broad, with its meaning shifting depending on context and time period, yet its core identity as a multi-movement work for one or more instruments has proven remarkably stable. A related concept, the sonatina (plural: sonatine), represents the diminutive form of the sonata, typically referring to a shorter or technically simpler piece. This distinction acknowledges that the sonata's structural DNA can be scaled down without losing its essential character. From Corelli's 17th-century trio sonatas to contemporary compositions, the sonata has served as a vessel for musical expression across every major era, adapting its internal language while preserving the architectural logic that made it one of the two fundamental organizing principles of concert music alongside the fugue.
