Sonata (Bach)

Sonata (/səˈnɑːtə/; Italian: [soˈnaːta], pl. sonate; from Latin and Italian: sonare, "to sound"), in music, literally means a piece played as opposed to a cantata (Latin and Italian cantare, "to sing"), a piece sung. The term evolved through the history of music, designating a variety of forms until the Classical era, when it took on increasing importance, and is vague. By the early 19th century, it came to represent a principle of composing large-scale works. It was applied to most instrumental genres and regarded—alongside the fugue—as one of two fundamental methods of organizing, interpreting and analyzing concert music. Though the musical style of sonatas has changed since the Classical era, most 20th- and 21st-century sonatas still maintain the same structure.

The term sonatina, pl. sonatine, the diminutive form of sonata, is often used for a short or technically easy sonata.

In the Baroque period, a sonata was for one or more instruments almost always with continuo. After the Baroque period most works designated as sonatas specifically are performed by a solo instrument, most often a keyboard instrument, or by a solo instrument accompanied by a keyboard instrument.

Sonatas for a solo instrument other than keyboard have been composed, as have sonatas for other combinations of instruments.

In the works of Arcangelo Corelli and his contemporaries, two broad classes of sonata were established, and were first described by Sébastien de Brossard in his Dictionaire de musique (third edition, Amsterdam, ca. 1710): the sonata da chiesa (that is, suitable for use in church), which was the type "rightly known as Sonatas", and the sonata da camera (proper for use at court), which consists of a prelude followed by a succession of dances, all in the same key. Although the four, five, or six movements of the sonata da chiesa are also most often in one key, one or two of the internal movements are sometimes in a contrasting tonality (Newman 1972a, 23–24).
