What were Antonio Vivaldi’s earliest published musical works?

Antonio Vivaldi’s earliest musical compositions date from his initial years at the Ospedale della Pietà. His first printed collections of musical works were:1

• Trio sonatas: Published in 1705.1
• Violin sonatas: Published in 1709.1

Following these, his first and most influential set of concerti for violin and string orchestra, titled L’estro armonico (Opus 3), was published in 1711. While Opus 3 is often cited for its role in establishing his international reputation, the trio and violin sonatas represent his earliest published works.12
