The word concerto first appeared in a music print title in 1587. This Italian term meant accord or gathering and derived from the Latin verb concertare, which indicated a competition or battle. In the late 16th century, the genre began as vocal music where voices and instruments interacted with independent parts. Giovanni Gabrieli composed sacred works like In Ecclesiis that exemplified this early form. Heinrich Schütz wrote Saul, Saul, was verfolgst du mich to demonstrate how instruments could accompany voices without merely doubling them. The instrumental variant emerged around a century later when Italians such as Arcangelo Corelli and Giuseppe Torelli started publishing their own concertos. By the time Antonio Vivaldi wrote hundreds of violin concertos, the genre had shifted decisively toward purely instrumental forms.
Baroque Innovations
Arcangelo Corelli developed the concerto grosso form using a concertino group consisting of two violins, a cello, and basso continuo. J.S. Bach expanded this structure in his Fifth Brandenburg Concerto by featuring a flute, a violin, and a harpsichord within the small solo group. The harpsichord sometimes played with the ripieno while functioning as a continuo keyboard accompaniment. Tommaso Albinoni and Georg Philipp Telemann followed Corelli's lead in establishing the Italian style. Antonio Vivaldi published collections including L'estro armonico, La stravaganza, Six Violin Concertos Op. 6, Twelve Concertos Op. 7, Il cimento dell'armonia e dell'inventione, Six Flute Concertos Op. 10, Six Concertos Op. 11, and Six Violin Concertos Op. 12. These works established the standard three-movement structure that would dominate for centuries. A slow movement like lento or adagio appeared between fast movements such as presto or allegro.
