Beethoven originally gave the name "Bonaparte" to the piece that became known as Eroica out of admiration for the French hero. But when Napoleon declared himself emperor, Beethoven angrily re-titled it Eroica, which means "Heroic." Tonight at 7:30 at Severance Hall, Jakub Hruša conducts the Cleveland Orchestra as it performs the piece. Performances continue through Sunday. Guest speaker Timothy Cutler of the Cleveland Institute of Music leads the pre-concert talk at 6:30 p.m. Consult the orchestra website for ticket prices and more details. (Niesel)
