Lieder und Gesänge is a collection of fourteen songs with piano accompaniment by Gustav Mahler. The title of the collection is sometimes given with the addendum aus der Jugendzeit (from the early days), but this addendum is not by Mahler. It is not even clear whether the subtitle refers to the songs being early works of Gustav Mahler (yet Mahler was aged 20 when he composed the earliest of the songs, not an adolescent), or whether the songs are meant to resemble memories of someone's younger days. The title might also simply refer to the source of the major part of the lyrics, Des Knaben Wunderhorn (The Youth's Magic Horn).
