変ロ短調
The Sérénade mélancolique in B-flat minor for violin and orchestra, Op. 26 (Russian: "Меланхолическая серенада"), was written by Pyotr Ilyich Tchaikovsky in February 1875. It was his first work for violin and orchestra, and was written immediately after completing the Piano Concerto No. 1 in B-flat minor.
