Riccardo Muti will become the Chicago Symphony Orchestra’s music director emeritus for life starting next season. The announcement was made on the stage of Orchestra Hall on Friday night after a performance of Beethoven’s “Missa Solemnis,” the start of Muti’s final subscription weekend as music director. His tenure began with the 2010-11 season.

Muti repeats the Beethoven on Saturday night and Sunday, then closes his tenure Tuesday night with a free concert in Millennium Park. Muti, who turns 82 in July, is scheduled to conduct the CSO for six weeks in each of the next two seasons. His CSO schedule for 2023-24 starts with two weeks opening the season in Chicago, two concerts to start Carnegie Hall’s season on Oct. 4 and 5.
