The canceled concerts in Rome will be replaced with a viewing of Leonard Bernstein's West Side Story accompanied by a live orchestra.
"I am very sorry," Morricone said Wednesday in a statement to fans, saying the concerts would be rescheduled.
A spokesman for the composer said that previously announced European tour dates will continue as planned, including concerts announced in Paris; Oxfordshire, England; and in Copenhagen later this year.

Morricone won his first competitive Oscar this year for scoring Quentin Tarantino's The Hateful Eight. At 87, he is thought to be the oldest Academy Award winner. He previously had earned an honorary Oscar from the Academy.
Over his 70-year career, Morricone has scored more than 500 film and TV shows as well as 100 classical works. Italian director and frequent collaborator Giuseppe Tornatore currently is directing a documentary about the composer's life and work.
