internationally acclaimed virtuoso of the basset horn, holds a major in clarinet with summa cum laude from the Conservatorio di Musica A.

It was Stockhausen who led Marelli to devote himself to the basset horn.
In October 2014 Marelli was awarded the prestigious Arthur Rubinstein Prize “Una vita nella musica giovani” together with the composer Salvatore Sciarrino.
