Contrast paragraph

It's pretty safe to say that, in the world of music, classical and rock are very different from each other. The first aspect in which they differ are the instruments used. Rock bands usually consist on guitarists, bassist and a drummer. In contrast, in a classical orchestra it is more common to hear violins, flutes, cellos and other string instruments. In addition, rock music usually has a lead vocalist who sings the lyrics to the songs, while classical pieces are mostly only instrumental. Another difference is the way they perform their music. Classical musicians are trained to play every note perfectly and they rehearse a lot to make everything sound good. On the other hand, rockers are not that worried about the technical aspect of the performance. This doesn't mean that they don't care about playing well, but not as rehearsed as classical bands. They're more focused in connecting with the audience and having a good time. To sum up, both types of music appeal to different people because at the end of the day, it is a matter of taste.
