Blockwerk
Blockwerk (Ger.), the pipework of a Gothic organ before the invention of registers, later broken up to form a rank of fundamentals with a *Vordersatz and a *Hintersatz, i.e., (mixture) pipes in front and behind it. Assuming an 8' pipe as fundamental, the pipes of a Blockwerk, sounded simultaneously, would have been (front to back, on one key) 1', 1⅓', 2', 2⅔', 4', 8', 4', 2⅔', 2', 1⅓', 1'. Aliquots were built up in this fashion on each key (161). Quoika, Rudolf. Altösterreichische Hornwerke…
