As the founder of the ensemble Il Suonar Parlante, he has explored not only early music but also jazz and popular music; as one of the most respected gambists in the world, he is co-author of a book on viol performance and music professor at the Conservatorio Luca Marenzio in Brescia, Italy.
In addition, Ghielmi regularly performs duet repertory with his brother, keyboardist Lorenzo Ghielmi and with lutenist Luca Pianca. Ghielmi’s major reportorial activity has been in the Baroque period, with particular focus on the works J.S. Bach, C.P.E. Bach, and Monteverdi. But Ghielmi, who is also a conductor, has performed contemporary serious works, too, such as Kevin Volans’ Matepe and White Man Sleeps, modern compositions both utilizing the viola da gamba.
