Giuseppe Maria Jacchini

Giuseppe Maria Jacchini (16 July 1667 in Bologna – 2 May 1727) was an Italian cellist and composer.

Jacchini received his musical training as a choirboy in the San Petronio Basilica in Bologna. There he studied composition with Giacomo Antonio Perti and Domenico Gabrielli. Later Jacchini became a cellist in the "cappella musicale" of the San Petronio Basilica. He is possibly the "Giosefo del Violonzino" referred to in the period from 1680 to 1688.

He composed mainly instrumental music with cello, violin, and keyboard continuo. He dedicated his opus 4 to Bolognese Count and composer Pirro Albergati, who had campaigned for Jacchini's permanent position in the orchestra of the cathedral of Bologna.

Jacchini became a member of the prestigious "Accademia Filarmonica" on 16 December 1688. He also served as conductor of the "Collegio dei Nobili" and the church of S. Luigi.

His cello works helped to strengthen the position of the cello as a solo instrument. As an excellent companion he played frequently at the theater in the city. His trumpet concertos prepared for celebrations at the San Petronio Basilica are in the tradition of the works of his teacher Perti, Giuseppe Torelli and Petronio Franceschini.
