Performances by Andrea Rast and Helen Kunz-Rast on Swiss TV and in concerts, have made them well know all over Switzerland! From a young age, they have played these wonderful, unique instruments, and now Helen's children are following in her footsteps.

The Schwyzeroergeli is a type of diatonic button accordion used in Swiss folk music. The name comes from the town/canton of Schwyz, where it was developed. Oergeli is the diminutive form of the word Orgel (organ). Outside of Switzerland the instrument is not well known and difficult to find.
