Seuerling wrote the song "Sång i en melankolisk stund" (English: Song in a Moment of melancholy) for harp music. The song was very popular in Sweden during the entire 19th century. It teams depression, suicide and betrayal, but also of the happiness of friendship and the hope it gives, interpreted as her own feelings when she was given tuition by Pär Aron Borg and her life changed. It begins: "No ray of light shine from above, the night was terrifying and darkness surrounded me...", and ends: "...then as the first ray of dawn a light broke through the mist and friendship came; and with its radiance calm and joy filled my heart."
