Weinberg’s Symphony No. 13, dedicated to the memory of his mother, is cast in a single movement that unfolds in a symmetrical arc. A large orchestra is used sparingly in chamber-like textures with motivic ideas that evolve over the course of the work. The result is music of gripping and unsettling power, both emotionally intense and architecturally complex. Some years earlier Weinberg wrote the light-hearted Serenade, Op. 47, No. 4 which offers a study in contrasts: by turn capricious, rumbustious and wistful.
