Davoud Shirazi and Ephraim Salzmann is playing Persian Santoor and Hackbrett in Santoor Center 

In September 2020, the beloved Swiss dulcimer (Hackbrett) player, Ephraim Salzmann, came to Tehran to hold a duet concert with Iranian dulcimer player Davood Shirazi in the garden of the Swiss Embassy. The video you see below is the result of just a few days of training and playing by these two musicians with two different instruments but with the same root, which was recorded in the yard of Santoor Center.
