1450-1600 - The rebirth of humanism...a revival of cultural achievements for their own sake.
This is the "rebirth" of humanism and a revival in cultural achievements for their own sake. In the Renaissance we see the beginnings of modern science and commerce.
Well written music in this era was not just for the masses and motets of Church services, but also for the secular areas, such as a new form of composition, theme and variations.
Also, instrumental music, which had long been closely associated with vocal music, became more independent.
The main changes, which define the musical Renaissance from about 1420, are the use of thirds as structural intervals, the accompanying concision of the musical lines, and the resulting path toward modern harmony.
Composers of this period include Byrd, Tallis, and Palestrina.
