With the decreasing influence of the church, composers of this time were beginning to compose highly decorated and elaborate melodies. I am a great fan of Purcell, Bach, Vivaldi, Telemann and Handel to name but a few. I love the contrasting music of this era, just take a look at the Fugues by Bach and Handel for example. Now I enjoy a good Fugue as much as the next person but I don't think anyone can argue that it was Purcell's compositions that heralded the beginning of this fantastic new era. (Of course, he seems not to have cared so much for the Air and Variations of which the Elizabethans were so fond.)
