Symphony No. 4 in F minor, Op. 36 and the Overture–Fantasy Romeo and Juliet are orchestral works by Pyotr Ilyich Tchaikovsky, completed in 1877 and 1870 respectively. Both pieces exemplify Tchaikovsky's late-Romantic idiom, featuring expansive, emotive melodies, rich orchestral colour and dramatic contrasts, with the Fourth Symphony exploring cyclical motifs and psychological intensity within his symphonic output while the overture translates Shakespearean drama into a programme-like, thematically contrasted orchestral narrative.
