A Meistersinger was a member of a German guild for lyric poetry, composition and unaccompanied art song of the 14th, 15th and 16th centuries. The Meistersingers were drawn from middle class males for the most part.

Minnesang was a tradition of lyric- and song-writing in Germany and Austria that flourished in the Middle High German period. This period of medieval German literature began in the 12th century and continued into the 14th. People who wrote and performed Minnesang were known as Minnesänger, and a single song was called a Minnelied.
