A symphony is a large-scale musical composition for an orchestra. It typically consists of several movements, each with its own tempo, mood, and structure. Symphonies are often considered to be the most prestigious form of orchestral music, and many of the most famous composers have written symphonies, including Beethoven, Mozart, and Tchaikovsky.
Tome
A tome is a large, heavy book, especially a scholarly or reference work. Tomes are typically found in libraries and archives, and they often contain valuable information that is not available elsewhere. Some of the most famous tomes include the Bible, the Encyclopedia Britannica, and the Oxford English Dictionary.
