The volynka (, , – see also duda, and koza) is a Slavic bagpipe. Its etymology comes from the region Volyn, Ukraine, where it was borrowed from Romania.
The volynka is constructed around a goat skin air reservoir into which air is blown through a pipe with a valve to stop air escaping. (Modern concert instruments often have a reservoir made from a basketball bladder}. A number of playing pipes [two to four] extend from the reservoir holding the air. The main playing pipe on which the melody is played has five to seven, sometimes eight finger holes. The other pipes produce a drone. This is usually either a single tonic note or a perfect fifth. Each of these playing pipes has a double reed usually made from a goose quill. In the 20th century this instrument has lost the popularity it had previously, and is rarely used today in an authentic context.
