Symphony No. 3 and Rhapsody on a Theme of Paganini are orchestral works by Sergei Rachmaninov, composed in 1936 and 1934 respectively. Both pieces sit firmly in his late-Romantic style, featuring rich orchestral colour, sweeping melodic lines and prominent piano writing, with the Rhapsody structured as a set of variations that foreground virtuosic piano passages and the Symphony representing his continued exploration of harmonic density and structural refinement near the end of his compositional career.
