I'd like to suggest for an Austrian entry on Sounds of the World series. The Zither seems to be a quite typical instrument for Austria, with the Salzburg and Wiener Zither being 2 very important variations of the instrument.

I've attached 2 examples of existing Austrian stamps of the instrument. Further information can be found here: https://de.wikipedia.org/wiki/Zither#Alpenl%C3%A4ndische_Zither

Would be nice for Austria to be included in this series.
