"Beim Arsch ist’s finster“/"Die Nacht ist finster“

Part-songs are non-contrapuntal musical settings for several voices, sometimes with accompaniment of a keyboard instrument or other instruments. Mozart only composed a small number of part-songs, mainly for private occasions in Vienna. The songs used at meetings of the Freemasons (see work group 31) stand between the part-song and the solo song because the last lines of the text are sung or repeated by a male chorus.
