Renaissance
The earliest surviving keyboard compositions (keyboard music was not instrument-specific until the sixteenth century) are from England (Robertsbridge Codex c. 1365) and Italy (Faenza Codex, 15th century).
The English virginal style was a manner of composition and performance prevalent in the sixteenth and early seventeenth centuries; some manuscripts are preserved in the Fitzwilliam Virginal Book. Sweelinck was strongly influenced by this style. Organ music was almost exclusively based on learned contrapuntal, exemplified by the Fantasia ("Fancy"), as well as works based on contrapuntal treatment of chant. Composers well known for their choral works wrote organ music, for example Tallis, Byrd and Gibbons.
