Trio sonata
Some of the best trio sonatas are those by Arcangelo Corelli.  His collection of trio sonatas numbered opus 1 and 3 are sonata da chiesa: four movements (slow-fast-slow-fast) finishing with a fugue.  His op 2 and 4 sonatas are sonata da camera type: each movement is a kind of dance.  Corelli’s trio sonatas are for two violins and continuo.
