Jazz orchestra musician Claudio Guarcello wears a face mask to curb the spread of COVID-19 before playing a rehearsal at the Giuseppe Verdi Music Conservatory, in Milan, Italy, Friday, May 7, 2021. Whatever the instrument, flute, violin or drums, students at Italy's oldest and largest music conservatory have been playing behind plexiglass screens during much of the pandemic as the Conservatory found ways to preserve instruction throughout Italy's many rolling lockdowns.
