Diogenio Bigaglia, also Padre Benedettino Bigaglia or Padre Bicajo in some manuscripts, (b. c. 1676 in Murano near Venice; † c. 1745 in Venice) was an Italian composer.
Diogenio Bigaglia entered the Benedictine monastery of San Giorgio Maggiore in Venice in 1694. He was ordained priest in 1700 and eventually became Prior of the monastery in 1713.
Bigaglia composed both sacred and secular vocal works. Little of his larger-scale sacred compositions survived but printed textbooks attest to performances of his oratorios outside Venice, including Rimini, Bologna, Faenza, and Prague. His numerous sacred and secular cantatas reveal the influence of Alessandro Scarlatti. His instrumental music - some concerti grossi and solo concertos, his 12 sonatas for violin or flute and b. c. op. 1 (published by Le Cène, Amsterdam, 1715), but especially the trio sonatas for 2 flutes and b. c., manuscripts of which are in Berlin and Schwerin - show Bigaglia to be a connoisseur of the contemporary styles of Germany and France. The aforementioned trio sonatas are set in the form of the church sonata and require a virtuoso flute technique in the ornaments; the lines are reminiscent of the works of Bach and Handel.
