Viol
The viol was popular in the houses of rich people, and in the royal court. During the reign of Elizabeth I and, later, King Charles I composers such as William Byrd, John Dowland, Orlando Gibbons, John Jenkins and William Lawes wrote viol music.  Solo sonatas were written by many composers including Marin Marais, Johann Sebastian Bach, and Karl Friedrich Abel.  Some of the last and greatest fantasies for viol consort were written by Henry Purcell.
