According to various encyclopedic sources, chamber music is a genre of music comprising works intended for performance by a small number of instruments, i.e., from 2 to 9, played solo. The name comes from 'camera' meaning room, thus implying the intimate character of this music. In the Baroque period, chamber music was understood more broadly - as a genre performed at the courts of princes, having an entertainment and concert character. Its emergence can be explained by the necessity to create a counterbalance to church and operatic music. It was only in the Baroque period that important forms of chamber music were shaped: instrumental sonata da camera and vocal cantata da camera. From these forms, chamber music in the modern sense began to develop in the pre-classical period, i.e., trio, quartet, quintet, etc., which are genres based on the classical sonata form scheme.
During the Classical period, chamber music became a favorite attraction of social life among the upper classes. At that time, many representatives of the aristocracy played instruments, and some compositions were created for them.
In the Romantic period, the lifestyle of the aristocracy began to resemble that of the wealthy bourgeoisie, and it became fashionable to practice chamber music in bourgeois homes. Around the harpsichord or piano, various sets of instruments were gathered.
In the 19th century, the concept of chamber music changed its meaning; it was no longer opposed to church and operatic music but to symphonic music. Over time, chamber music found its way to concert stages.
In the 20th century, chamber music continued to attract the interest of composers. There was a significant diversification of chamber ensembles, for example, percussion elements began to appear more frequently in them (B. Bartok).
