Trio sonata


The trio sonata is a genre, typically consisting of several movements with two melody instruments and continuo. Originating in the early seventeenth-century, the trio sonata was a favorite chamber ensemble combination in the Baroque era.

Basic structure

The trio sonata typically consisted of three parts, two violins and a continuo. However, the two violins could be substituted with pairs of flutes, recorders, or oboes. The second part, the basso continuo, has two parts. First, it includes the bass line, which most commonly was provided with a bass viol, violone, violoncello, or bassoon. Second, it includes a harmony-producing instrument, such as a small organ, a harpsichord, or a theorbo. The continuo could be performed by two or more performers; a cellist to play the bass line and a harpsichordist or organist to focus on the harmonies. Because there normally are two people playing the continuo part, there are usually four players in all. This can be misleading to some as the "trio" of the trio sonata refers to the three parts and not the number of players. From about the middle of the 17th century two distinct types of sonatas appeared: sonata da camera and sonata da chiesa . The chamber sonata was considered a group of stylized dances and church sonatas were much more serious and typically arranged into a slow-fast-slow-fast sequence.

Composers, compositions and variant formats

The genre originated as instrumental adaptation of the three-part texture common in Italian vocal music in the late 16th century. The earliest published trio sonatas appeared in Venice and in Milan .

Arcangelo Corelli

Italian composer Arcangelo Corelli was one of most influential composers of the trio sonata. The published trio sonatas by Corelli are :
An additional collection of Trio Sonatas, for two violins, cello, and organ, was published as "Op. post." in Amsterdam, in 1714. Corelli's trios would serve as models for other composers well into the 18th century.

Johann Sebastian Bach

German composer Johann Sebastian Bach is another notable composer of the trio sonata, but he was known for shying away from the traditional structure of the sonata. He typically played the three parts with fewer than three instruments. One part could be played by a violin and the other two parts could be played by a keyboard, or all three parts could be played on the organ.
