However, there are at least two more specific historical meanings: 1) the fantasia/fantasie/fancy of English Renaissance viol consort music and 2) Cobbett's Phantasie, an early 20th century form of single-movement chamber music inspired by the Renaissance fancy with the goal of stimulating new English chamber or "consort" music.
sonata, sonate, suonato—a complicated term. Originally, "sounded" rather than "sung" (sonar vs. cantar), e.g. instrumental music. According to historical period, sonata began to imply a formal plan of movements as well as the structure within a single movement, e.g. sonata form. In general usage as a work title, it designates a multi-movement piece for solo or duo instruments with one of the instruments enjoying a feature role.
