These names, of which Salicional is by far the most common, derive from the Latin salix, meaning �willow�. Salicis Fistula means �willow pipe�, a rustic flute made from a branch of a willow tree. Dating from the late 15th century, it was originally, according to Williams, rather flute-like in tone, but later evolved into a string stop whose tone varied considerably across centuries and continents. In the 17th century the Salicional was a specialty of Habsburg Europe, from which Snetzler brought it to England where it became very popular in the 19th century. Wedgwood tells us that the German Salicional was a �horny� string, the French variety a quiet Diapason, and the English variety a slightly stringy Dulciana. Bonavia-Hunt and Maclean describe its ideal tone as an echo Geigen. Skinner claimed the Salicional as a stop native to America, and voiced it more keenly than his Gambas. Now one of the most common string stops, it is most often found at 8' pitch, but can also be found at 16', 4', and rarely 2'. At 8' pitch it is often accompanied by the Voix Celeste. While some sources consider it to be a synonym for Salicional, most sources define Salicet as a Salicional of 4' pitch. Weidenflöte may or may not be a synonym.
