Undeservedly overshadowed by his two string quartets and piano trios, the small pieces for violin or cello and piano are among the best of their genre from the “Moscow School”, differing mainly by having partly salonesque titles and a more intimate expression. The Quintet in D major Op. 51 (1900) for piano, two violins, viola and cello exemplifies the 40-year-old composer’s mature style, its cyclic elements and formal density heralding a new departure. The priority given to the piano and the variation movement suggest the influence of Tchaikovsky’s Piano Trio in A minor Op. 50.
