The Cleveland Orchestra is hiring a new head of symphony for 2019.

The move comes after two decades as a part-time employee, and comes after an unsuccessful attempt to acquire the music of the Boston Symphony Orchestra, whose founder, Roberta Wilson, died in 2017.

The orchestra announced in March that it was going to sell the orchestra, which has performed more than 500 concerts worldwide, to Chicago-based JBL Music Group.

The news came on the heels of a successful effort by the Cleveland Orchestra to buy a controlling interest in the Boston orchestra, where Wilson’s brother, Ed, is the chief executive officer.

Wilson’s widow, Dorothy Wilson, said at the time that she had hoped the orchestra would someday be able to find a permanent home for its music.
