Which of the following best describes Sammartini's Symphony No. 13?

• A. One of the first standing concert symphonies with strings and basso continuo in four movements
• B. A late Romantic symphony with a choir
• C. A solo piano concerto
• D. An opera overture

Answer: (A)

Sammartini’s symphonies sit at an important transitional moment in musical form: instrumental sinfonias in Italy that are primarily for strings with a continuo part, often performed in concert settings, and many move toward a four-movement layout. Describing Symphony No. 13 as a four-movement work for strings with basso continuo matches this pattern, showing the early, concert-focused instrumental style that helped shape the modern symphony. The other options lead to later or different genres: a late Romantic work with a choir belongs to a century later and to vocal-orchestral writing, a solo piano concerto centers on a keyboard solo rather than an ensemble, and an opera overture would usually be a single, introductory piece rather than a full multi-movement symphony.
