THE CLASSICAL PERIOD (1775-1825). The Baroque period culminated in the masterpieces of J.S. Bach and G.F. Handel. In the middle of the eighteenth century, contemporaneous with the mature years of Bach and Handel, a new musical style developed that is known as Rococo or preclassical style.he music of the Classical era is characterized by objectivity. While emotion is an important aspect of all music, in the Classical period, emotions were carefully controlled. This control is evident in the use of dynamics and expressive differences within sections or movements of a composition.
The same thing happens to a rock when it is heated enough. Of course, it takes a lot of heat to melt a rock. The high temperatures required are generally found only deep within the earth. The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper.
Metamorphic rocks are sedimentary or igneous rocks that have been transformed by pressure, heat, or the intrusion of fluids. The heat may come from nearby magma or hot water intruding via hot springs. It can also come from subduction, when tectonic forces draw rocks deep beneath the Earth's surface.
