Nocturne (String Orchestra, arranged by Merle J. Isaac, Grade 3) is derived from Alexander Borodin’s String Quartet No. 2. This arrangement preserves the beloved melody, lyrical counterpoint, and rich textural elegance of the original, while adapting it to be technically accessible and emotionally expressive for intermediate string ensembles. It’s a memorable showpiece that beautifully balances sophistication and playability.
