Explanation: In the Renaissance and Early Modern Period, European warfare changed radically. The noble heavy cavalry which had previously dominated both the battlefield and social structure of European states was increasingly rendered obsolete by well-trained groups of infantry, often men serving as mercenaries, in the vein of Swiss pikemen and German Landsknecht (or the slightly-later Spanish Tercio, made up of volunteers for a national army - a big innovation!) With pikes that were 4 meters+ long, and enough discipline and orderly movement, these infantry could present impenetrable walls of pointy metal bits that even heavy cavalry charges could not break. Common-born professional soldiers increasingly decided the ultimate fate of nations, not the knightly aristocracy.

In line with this new method of warfare based on infantry coordination, European military music began to take on more distinctive forms in order to assist maintaining a steady pace in formation, just as the Ottoman Turkish Janissaries had introduced a few decades earlier - with drums in particular becoming prominent to maintain a good marching beat!
