Buxheimer Orgelbuch

The Buxheim Organ Book (German: Buxheimer Orgelbuch) is a manuscript created around 1460/1470 with 256 original compositions and arrangements for keyboard instruments for the Buxheim Charterhouse in Germany, in today's district of Unterallgäu. Most of the composers are anonymous, but some are also known composers of the time (e.g. John Dunstable, Guillaume Du Fay, Gilles Binchois, Walter Frye, Conrad Paumann).
