During his career, how many Italian operas and symphonies did Haydn compose roughly?

• A. 5 Italian operas and 30 symphonies
• B. 20+ Italian operas and 70+ symphonies
• C. 10 Italian operas and 20 symphonies
• D. 50 Italian operas and 150 symphonies

Answer: (B)

Haydn’s output shows a clear balance: a vast body of instrumental music, especially symphonies, paired with a substantial but smaller set of Italian operas. He wrote roughly twenty or so Italian operas and well over seventy symphonies. The scale is what matters here—the symphonies dominate the catalog, while the Italian operas are numerous but fewer in number. That’s why this pairing fits best as a rough, general estimate for his career.

Other totals would either undercount the operas or undercount the symphonies (or overstate both), which doesn’t align with the familiar view of his prolific orchestral work alongside a significant but smaller operatic output.
