A mixture of from two to six ranks, intended to imitate or suggest the sounds of bells. It usually contains one or more third-sounding ranks, voiced somewhat prominently. Audsley describes its characteristic features as being its scaling and voicing, and reports that good examples have been made by Cavaillé-Coll. Grove describes it as �an important Dutch Tierce Mixture found c1750-1850 as a kind of Echo Cornet�, and Williams adds that at that time and place it was composed of 3 ranks and found on Ruckpositiv divisions. Skinner defines it as a three-rank mixture consisting of a 12th, 17th and 22nd, breaking back in the top octave to a 5th, 10th and 15th, and composed of mild Gamba ranks of scale 56 to 58. There are also percussion stops that goes by the names Carillon and Clochette[s] or Glockenspiel.
