A Koza is a Polish bagpipe. The Polish pipes are more related in appearance to some old German pipes. It uses a large goatskin bag (hair out) and a single reed chanter, cylindrical bore and deep pitch, with a large horn and brass bell at the end. The bass drone typically has the same bell. It is usually bellows-blown and produces a mellow, low pitch. A carved goatshead stock similar to the duda is common. The single reeds are often made of a cane blade lapped onto copper tubing.
