Which types of Classical instrumental works commonly use sonata form?

In the Classical period, sonata form became the primary structural method for the first movements of many multimovement instrumental works. It is most strongly associated with the following genres:12

• Sonatas: Typically written for a solo instrument or a small ensemble, these works often utilize sonata form in their opening movements.123
• Symphonies: Often described as sonatas for orchestra, symphonies frequently employ this form in their first movements and occasionally in their final movements.124
• Chamber music: This category includes works such as string quartets, piano trios, and string quintets, all of which are based on structural principles similar to those found in the string quartet.24

While sonata form is most common in the first movement, it can also appear in other movements of these works, including slow movements or finales, often adapted to suit the specific tempo and character of those sections.134
