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.
The pressure within the earth is the result of gravity pulling the crust of the earth downward.Like heat, pressure increases with depth. This pressure can actually squeeze the spaces out of the minerals within the rock. This makes the rocks denser. The heat and pressure together cause the rock to flow instead of break or fracture. The mineral grains become realigned. They flatten out and get longer. Sedimentary rocks exposed to this kind of heat and pressure are transformed into new kinds of rocks. Limestone changes to marble. Shale changes to slate. Back to The Rock Cycle
