Comparative paragraph: Sex Pistols vs Mstislav Rostropovich

Today it is too easy  create one song and  continuously we discovered new musical genres. But my entry of this week is dedicated only in two big genres: The rock group of Sex Pistols and the classical music of Mstislav Rostropovich. To start, in terms of the instruments that each one uses, we can see that this group of rock creates their songs with an electric guitar and drums to do the rhythm while the classical music of Mstislav Rostropovich employs a cello and with an orchestra they use another kinds of instruments like the violin or the contrabass. Regarding of the voice, the rock music tends to employ  high and sharp voices while the classical music usually is not accompanied with a background voice. The clothes that both genres wear are completely different because in  one hand, the rock group usually wear casual clothes and on the other hand, the classical music employs very smart clothes (although we have seen some rock groups like The Rolling Stones that used costumes in their concerts). Appart from the opposite things, there are points in comun. For example, they employ musical notes to create their songs. In short, there are very different genres but at the end both are music which do our lives more bearable according to the taste of each person.
