There are many arts in the world, but the most popular are: literature, music, theatre, cinema and others.
Music has always touched hearts and makes people laugh or cry. Nowadays there are a lot of musical genres: classical music, rock music, pop music and others. I can listen to any genre of music. When I am sad, I listen to classical music. When I am happy, I like listening to energetic, fast music and hard beat. However, some people listen to one kind of music only and they listen to it no matter what mood they are in. There are a lot of wonderful works of literature. Famous writers create poems, stories, novels. But I am fond of science-fiction, fantasy and adventure books.
My favourite art is painting. I enjoy going to art galleries to look at paintings. I think that this type of art will exist forever. Artists express their feelings and emotions in their paintings.
My favourite genre of painting is landscape. I love going to the gallery when I have free time. One of my friends draws very well. She is going to study in the University of Arts to become a professional artist. Unfortunately, I do not have any talent for this. I used to sing in childhood, but then I gave it up. I think that arts are not for me.
