About work: Nocturne is Bella's last composition for string quartet and one of his final works of any kind. The work embodies a balanced harmony of the composer's classical and Romantic leanings. While the tectonics of the composition suggest some kind of miniature sonata-cycle model (sonata form - song form - final rondo), the suppression of contrasting elements within the individual movements brings out in them an evolutionary fantasy quality which accents Romantic affinities. The composition includes two quotations of Slovak folk songs: "A Horse Runs along the Bank" and "Good Night, My Love".
