[1] According to the eighth volume of the Garland Encyclopedia of World Music, illustrations dating back to the 1300s and 1400s suggest that the instrument consisted of a simple bag made from a bladder, as well as a single-piece, often conical, chanter.
By the 1450s–1550s, the most common model of the pipasso was made from a sewn bag, a one-piece conical chanter, and also included a two-jointed bass drone (see bagpipes for technical definition of drones as they pertain to musical instruments).
The single surviving model is currently held in the Kunsthistorisches Museum in Vienna, Austria.
Though documentation of the instrument dates back as far as the fourteenth century,[1] today very little information about the pipasso circulates among the public and the academic realm of music studies.
However, several groups are working to make the instrument visible and known to the general public, including Amuséon and ch'Pipasso Greench Binde.
