what is a sonata

A sonata is a type of musical composition that is played by an instrument or instruments, as opposed to being sung. The term "sonata" comes from the Italian word "sonare," which means "to sound". The meaning of the term has evolved over time, but it has always referred to compositions that are played by instruments. A sonata typically consists of two to four movements or sections, each in a related key but with a unique musical character. The musical style of sonatas has changed since the Classical era, but most 20th- and 21st-century sonatas still maintain the same structure. The term "sonatina" is often used to describe a smaller or simpler sonata. It is important to note that "sonata" should not be confused with "sonata form," which is a specific structure used in many sonatas.
