Skudučiai is a set of one of the most popular Lithuanian folk instruments. The set consists of several different sized tubes, each of them producing a particular pitch. Nowadays this instrument is mostly made out of wood (ash or maple), although back in the days musicians used various hollow plants, such as ground elder, chervil, wild celery, elderberry etc. Traditional Lithuanian skudučiai were not tied together, but played separately by a group of several musicians, creating a harmonious polyphonic melody.
