The Trancanholas MISSOM® are produced in various woods such as Hard Maple, Hickory or Ipe (in ascending order in density), with 1,57 inch to 1,97 inch wide and 4,53 inch long. The Trancanholas, also named as Castanets of Amarante - Douro, consists in two symmetrical blades that are used in a way similar to the usual castanets, usually by men dancing in some festivities of Northern Portugal. In this case, the blades allow running with just one hand, leaving the other free. "In Amarante and Lower Douro to Porto, the castanets are of this type: simple tables small and elongated tucked between the index and middle fingers and between this and the ring, so that, shaking hands, they clash up." - Oliveira, Ernesto Veiga, "Popular Musical Instruments Portuguese". Dimensions: 1,77 inch X 4,53 inch.
