Pibgorn (Welsh lit. "pipe horn")- A number of examples of this instrument survive, these date from the 17th and 18th centuries. The pibgorn is a mouthblown hornpipe, having a parallel bore, six finger holes and a thumb hole. The pipe has a cowhorn mouth piece and an intricately carved cowhorn bell. The reed is of the single beating type usually made of cane but some players now use synthetic reeds. Modern pibgyrn (pl.) play in the key of D using open fingering, with many tunes in E minor.
A further development (probably a redevelopment) of the pibgorn are the pibau cyrn where the pibgorn is played with a mouthblown bag and a bass drone playing an octave below the tonic
Another development of piping in Wales has been the making of mouth blown pibau cwd, pibgwd or bacbib which are based on the veuze and Galician gaita. They have a steep conically bored chanter with seven finger holes and thumb hole with a double reed and a single base drone usually tuned two octaves below the tonic. Drones are also tuned to one note below the tonic for minor tunes. Welsh pipers most often play bagpipes in the key of D but other keys are also used, particularly C or B#.
