Suite No. 1, Op. 43 (1878) and Suite No. 4, Op. 61 “Mozartiana” (1887) are orchestral suites by Pyotr Ilyich Tchaikovsky. They juxtapose Tchaikovsky's lush Romantic orchestration—marked by expansive melody and rich harmonic colour—with a later work that consciously references Classical-era forms and textures, characterising a late-career engagement with restraint and homage to earlier styles.
