You might think that Christmas Eve would not the best night to attract an audience to a classical music concert. Think again.
The New York String Orchestra, conducted by Jaime Laredo, played its annual Christmas Eve concert at Carnegie Hall, and the place was nearly full. Well conceived for a holiday evening, the 60-minute program started at 7 and featured two works by Mozart along with a Mendelssohn novelty: the Concerto for Violin, Piano and Strings in D minor — an exuberant, appealing and precocious work written when the composer was just 14. The outstanding soloists were the violinist Jennifer Koh and the pianist Benjamin Hochman.

The New York String Orchestra is an unusual venture that has attracted a loyal following. The core of the program that resulted in Friday’s concert is an intensive 10-day training seminar for young musicians, established in 1969 for the violinist and conductor Alexander Schneider and continued after his death in 1993 by Mr. Laredo. This year 64 students ages 16 to 25 from across the United States and Canada have been brought to New York for chamber music workshops and coaching sessions with master musicians.
Every year two orchestra programs are prepared during the seminar and performed at Carnegie Hall. The orchestra routinely attracts major soloists for these programs, as it did last year when Peter Serkin played the Brahms D Minor Concerto.
The audience on Friday was fortified by many parents of the players, as was clear from all the flashing cameras in the hall when the students walked onto the stage. Mr. Laredo began with Mozart’s Overture to “Così Fan Tutte,” a buoyant, lively performance in which the strings were especially good, playing with full-bodied sound and solid execution.
