Most parts of Europe had active and well-differentiated musical traditions by late in the century. In England, composers such as Thomas Tallis and William Byrd wrote sacred music in a style similar to that written on the continent, while an active group of home-grown madrigalists adapted the Italian form for English tastes: famous composers included Thomas Morley, John Wilbye and Thomas Weelkes. Spain developed instrumental and vocal styles of its own, with Tomás Luis de Victoria writing refined music similar to that of Palestrina, and numerous other composers writing for the new guitar. Germany cultivated polyphonic forms built on the Protestant chorales, which replaced the Roman Catholic Gregorian Chant as a basis for sacred music, and imported the style of the Venetian school (the appearance of which defined the start of the Baroque era there). In addition, German composers wrote enormous amounts of organ music, establishing the basis for the later Baroque organ style which culminated in the work of J.S. Bach. France developed a unique style of musical diction known as musique mesurée, used in secular chansons, with composers such as Guillaume Costeley and Claude Le Jeune prominent in the movement.
