The collection was named by its first publisher Tobias Haslinger, presumably wishing to present it as Schubert's final musical testament to the world.
"Ständchen" ("Serenade") is the no. 4 in the manuscripts, whose song uses the text from Ludwig Rellstab. In music, a serenade (/ˌsɛrəˈneɪd/; also sometimes called a serenata, from the Italian) is a musical composition or performance delivered in honor of someone or something. Serenades are typically calm, light pieces of music.
