According to the literature, these names indicate a flute stop of 1/2' (6"), 1' or (according to Wedgwood) 2' pitch, which breaks back every octave like a mixture rank. There are, however, other meanings for the names Glöckenton and Glöckleinton, for Campanella, and for Campanello, which has been used as a synonym for Glockenspiel and Chimes. The name Campanella is mentioned only by Wedgwood, Zimbelflöte is mentioned only Irwin, and Campanelli and Campanilla are mentioned only Sumner. All of the names derive from words meaning �bell�, except for Tonus Fabri, which derives from the Latin faber, meaning �blacksmith�. The tone of this stop is thus intended to be suggestive of bells or of a hammer striking an anvil. Actual usage of these names differs from the definitions given in the literature: most are mixtures (see examples below).
