Schreipfeifen / Schryary

This instruments (mentioned as Rauschpfeifen too) were developed on the base of my shawms.
Despite their windcap, they are able to overblow just to the twelfth.
The sound is very loud and screaming (hence tha name), especially the smaller instruments.
They are open-air-instrumentst at is best, very suitable with bagpipesand percussion, for music of the middle ages and folk music.
