Una Furtiva Lagrima is a brilliant arrangement by Jacob de Haan, of the aria from Gaetano Donizetti’s opera L’Elisir d’Amore (The Elixir of Love) for concert band. The subject of this song is the power of love: Nemorino, the main character of the opera, sings the aria as he notices that his love potion is starting to take effect on his beloved. A furtive tear (Una Furtiva Lagrima) betrays his beloved’s feelings towards him in this emotional piece.
