He was a student of
Conservatorio della Pietà dei Turchini from 1693, where he became a cello virtuoso. He was the author of a manuscript didactic collection of toccatas for the instrument, with an explanatory introduction, entitled:
Principij da imparare à suonare il violoncello e con 12 Toccate à solo, found and published by the musicologist and cellist Luigi Silva (1903–1961). A copy of the manuscript is kept in the Biblioteca
Conservatorio San Pietro a Majella, Naples. In this work Supriani already uses the fifth position, as well as the bass and tenor clefs. As a virtuoso cellist, he helped the cello to emerge from its traditional rank of continuo and reach the elevated status of a solo instrument. Supriani is considered one of the teachers of
Francesco Alborea, commonly known as "Franciscello". == Compositions ==
