Since 1989 Firmament Musik belongs to the Meisel Group of Companies. Up to now Meisel runs the business of distributing sheet music as one of the last music publisher in Germany. Firmament came up to be an absolutely reliable service provider for musician suscriptions and the distribution of sheet music for light music / easy listening. Besides own material like the repertoire of Kollo, Meisel Evergreens and German Schlager, Firmament distributes sheet music by other music publishing companies and is proud of the trust offered by companies like Birnbach, Budde, Schacht, Schaeffers and George Glueck Music.

In addition to that Firmament realises the production and distribution of books of music by smaller music publishing companies, which do not have the opportunity to produce their books of music on their own. As a result songbooks of Rosenstolz, Matthias Reim, Keep Cool Musical and as well Ein Sommernachtstraum by Heinz Rudolf Kunze were produced. The genres of the distributed sheet music ranges from classical music, music for schools, German Schlager, pop music up to contemporary music. As well new media as for instance midi-files or other sound mediums are produced and distributed by Firmament.
