A common structural element in classical music, this refers to a specific type of movement, typically the third, in a four-movement work such as a symphony, sonata, or string quartet. It comprises two distinct sections. The first section features a graceful, moderate triple meter dance, while the subsequent contrasting section, often lighter in texture, is referred to as the trio. The initial dance section then returns, completing the composite form.
This structural arrangement provided composers with a means of achieving contrast and balance within a larger work. The dance provided a familiar and elegant framework, while the contrasting section offered respite and a change in character. Historically, this particular form evolved from courtly dances and became a standard feature of instrumental compositions from the Classical period onward. It allowed for both formal structure and creative expression, influencing the overall character of the complete piece.
