an Italian composer. Gnecco began studying the violin with Giacomo Costa (known conductor and choirmaster at S. Lorenzo, teacher of Niccolo Paganini, Serra and Sivori), and later studied composition with GL Mariani (1737-1793), Kapellmeister in Cathedral of Savona. Gnecco's output consists of a number of compositions, mostly for chamber ensembles. He achieved international success with The test of a serious opera, originally written in one act libretto by Artusi in 1803 under the title The first evidence of a serious opera, and divided into two acts, with libretto also by Gnecco, in 1805 .
