Symphony is a genre of classical music that originated in the late 18th century and continues to be a popular form of orchestral music today. It typically consists of four movements and is written for a full orchestra, which includes strings, woodwinds, brass, and percussion.

At its core, a symphony is a complex and harmonious composition that tells a story through music. Each movement of a symphony has its own character and mood, ranging from lively and joyful to somber and contemplative. The first movement is usually the longest and is typically characterized by a fast tempo and a sense of urgency. The second movement is often slower and more lyrical, while the third movement is typically a minuet or a scherzo and has a lively, dance-like quality. The fourth movement is usually the most dramatic and features a grand finale that brings the symphony to a satisfying conclusion.
