Listed only by Irwin, who says: A stop-name used to refer to a variety of Flute tones at either 8' or 4' on the manuals. The smaller-scaled Waldflöte or Orchestral Flute fulfills this definition in tone, but this Flute de Bois sounds other elements as well. The full-toned, smooth effect of the Clarabella is in it, as well as some horn-like overtones; other examples are said to have a �woolly� indistinct timbre. It has also been made at 2' and 1', and heard in all divisions as a solo or ensemble voice. A well-polished upper lip or pipe-front of hardwood with rounded shape aids in making this unique tone quality.
All known examples are listed below.
