Lisa de la Salle was the featured pianist playing with the Columbus Symphony this past weekend. Playing Mozart’s Concerto No. 20 in D Minor for Piano and Orchestra, K. 466 with Junichi Hirokami conducting, she concluded her solos with a flourish twist of her left hand. This piece was played with 37 musicians. The evening’s first piece, Stravinsky’s Concerto in E-flat Major for Chamber Orchestra, “Dumbarton Oaks,” featured only 15 musicians, the first, and sometimes second, chairs of core instruments. Schubert’s Symphony No. 5 in B-flat Major, D. 485 concluded the evening’s performance with 50 musicians on stage. The concert’s three pieces involved fewer musicians than any other concert in my memory. Is this foreshadowing of where the Columbus Symphony is headed? On the other hand, more seats of the Ohio Theatre were filled than I’ve ever seen.  To continue hearing live classical music in Columbus will take a significant benefactor or two.
