Song Cycle

A song cycle is a group of songs designed to be performed in a sequence as a single entity. As a rule, all of the songs are by the same composer and often use words from the same poet or lyricist. Unification can be achieved by a narrative or a persona common to the songs, or even, as in Schumann's second Liederkreis, by the atmospheric setting of the forest. The unity of the cycle is often underlined by musical means, famously in the return in the last song of the opening music in Beethoven's An die ferne Geliebte.

The term originated to describe cycles of art songs (often known by the German term "Lieder") in classical music, and has been extended to apply to popular music.
