Classical music refers to a broad genre of Western art music that has been in existence for several centuries. It is characterized by its complex and sophisticated melodic, harmonic, and rhythmic structures, as well as its use of various instruments such as strings, woodwinds, brass, and percussion. The term "classical" generally refers to the music composed between the mid-18th century and early 19th century in Europe, which is often considered the peak period of classical composition. Some famous composers from this era include Wolfgang Amadeus Mozart, Ludwig van Beethoven, and Johann Sebastian Bach. However, the phrase "classical music" can also be used more broadly to refer to any Western art music that follows in the tradition of these great composers, regardless of when it was written.
