Muchosa
From Wikipedia, the free encyclopedia

The muchosa is a type of bagpipe dating back to the late 13th century in Hainaut, Belgium and northern France, where it is known as the pipasso.[1][2]
The muchosa has a chanter with a conical bore and double reed, pitched to B-flat.[1] It has two single-reed drones.[1] The treble drone is placed in a common stock with the chanter, and the bass drone is placed further back in its own stock, a feature common to other the musette style of bagpipe in central and northern France.[1]
