What is the secondary movement of a standard Classical symphony usually like?

The secondary movement of a standard Classical symphony is typically characterized by being slow and lyrical. This movement, often referred to as the "slow movement," serves as a contrast to the surrounding fast movements, allowing for expressive and melodic content. Composers during the Classical period, such as Haydn and Mozart, utilized this slower tempo to explore deeper emotional themes and showcase the beauty of lyrical lines, often featuring elegant melodies that allow for greater expression and introspection.

The slow movement often employs various forms, including theme and variations, and provides an opportunity for the strings and woodwinds to shine, illustrating the nuances of orchestral texture and dynamics. This contrasts with the energetic character typically associated with the fast movements, reinforcing the overall emotional architecture of the symphony.
