Explanation: Chamber music is music performed by a small team of instrumental musicians and / or vocalists. When performing a chamber composition, as a rule, only one instrument or voice plays each part, unlike orchestral music, where there are groups of instruments playing in unison.

Currently the term is used for any song performed by a small number of musicians. The word camera indicates that music can be played in small rooms, usually with a more intimate atmosphere. Its composition is intended for a small number of instruments or voices - usually up to a maximum of ten.
