Johannes Brahms always made the singer’s part more important than the piano part. He learned a lot by studying Schubert’s songs and wrote some very famous Lieder. One of his best is the humorous "Vergebliches Ständchen" ("Serenade in vain"). His "Four Serious Songs" are very powerful. His famous "Wiegenlied" ("Lullaby"), a tune which everybody knows, is one of his songs.
