Nacht und Träume in the context of "Submediant"

An art song is a Western vocal music composition, usually written for one voice with piano accompaniment, and usually in the classical art music tradition. By extension, the term "art song" is used to refer to the collective genre of such songs (e.g., the "art song repertoire"). An art song is most often a musical setting of an independent poem or text, "intended for the concert repertory" "as part of a recital or other relatively formal social occasion". While many vocal music pieces are easily recognized as art songs, others are more difficult to categorize. For example, a wordless vocalise written by a classical composer is sometimes considered an art song and sometimes not.

Matthäus Casimir von Collin (3 March 1779 – 23 November 1824) was a leading poet in Vienna. Some of his works have been set to music by Schubert, such as Licht und Liebe (D.352), Der Zwerg (D. 771), Wehmut (D. 772) and Nacht und Träume (D. 827).

Matthäus Casimir von Collin was born in Vienna, the younger brother of the Viennese poet and playwright Heinrich Joseph von Collin.
