Listening to music is the favorite pastime of many people all over the world. This is especially true for
people living in Vienna, the city of song. Being the home of Mozart, this city is the birthplace of classical
music and the waltz.
Music fills the air in Vienna. Going to public concerts is often free of charge. And don't forget, Vienna is
also home to the world famous Vienna Boys' Choir. No wonder people say Austria is always alive with the sound
of music.
