Ludwig Van Beethoven was a musical genius that assumably everyone has heard of and recognizes as one of the most popular Classical musicians of all time.  He was a successful composer by the age of 30 despite losing his hearing and eventually becoming deaf by the age of 35.  His Piano Sonata No. 14 in C-sharp minor “Quasi una fantasia”, popularly known as the Moonlight Sonata was completed in 1801 in Vienna, and was rumored to be dedicated to a pupil of his that he was supposedly in love with.  He included the phrase “Quasi una fantasia” in the title, which means “almost a fantasy” because the first movement is not in regular sonata form, and where the three or four movements are arranged in a fast-slow-[fast]-fast sequence, the Moonlight sonata possesses an end-weighted trajectory; the climax is held off until the third movement (Wikipedia).

The following is a link for the piece and while listening to it, one can hear the simplistic yet emotional notions of the music and realize that anyone would find this enjoyable and calming.  During the Classical era, the middle class were uprising and demanding art, music and theatre that could be enjoyed by all classes, not just aristocrats and those of wealth.  Beethoven made many, many compositions which could be and were enjoyed by the middle class as well as those that were in other classes at the time.  Today, Beethoven and other Classical musicians provide anyone who wants to listen with a kind of art that is stimulating yet relaxing and definitely enjoyable.
