VIENNA — Alma Deutscher has not yet become a household name, but it seems only a matter of time.
An accomplished pianist and violinist, she is also a composer, having written concertos for piano and violin and an opera. In December, she will make her debut at Carnegie Hall, where she will play the solo violin and piano in her two concertos, while the orchestra will play selections from her opera and her most recent work, a Viennese waltz. Next month, she will record a retrospective album with Sony of piano melodies she composed going back to when she was just 4 years old.
