Where did classical music originate?

Music is often divided into several categories or groups. Some of the categories are: classical music, traditional music, rock music, and jazz music.
    The first kind, classical music, refers to orchestra music that originated in Europe a few hundred years ago. Most of the original classical music was composed, or written, in Italy, Germany, Austria, or Russia. Beethoven and Bach were two famous composers of classical music. Classical music is usually played by a variety of string instruments, such as the violin, and by a variety of wind instruments, such as the flute.
    The second type of music is traditional music. Traditional music is music that comes from a particular culture. Every culture has its own special forms of traditional music. For example, "blues" music is one kind of traditional music in the United States and "enka" music is one kind of traditional music in Japan. Each culture has its own traditional music, and its own special instruments for playing its traditional music. Another kind of music is rock music. Rock is generally a loud kind of music, played with a strong beat. Rock musicians often use electric instruments, such as electric guitars and electric pianos, but other instruments can also be used. Rock music probably began in Europe about 30 or 40 years ago. Rock became very popular, especially among young people, during the 1960s and 1970s.
    The fourth kind of music is jazz. Jazz probably comes from Africa originally. Jazz has a different kind of rhythm from other kinds of music. A variety of musical instruments are used to play this kind of music, especially wind instruments such as the trumpet and saxophone. Often piano, bass, and a variety of percussion instruments are also used. These are the four general types of music. Of course these definitions are brief and general, and certainly there are other categories of music. In addition, many kinds of music are combinations of classical and traditional, or classical and jazz, or rock and jazz, and so on.
