I am glad to introduce you my musical instrument GUDA drum hybrid. The main difference between this model from the standard is the presence of ding on the sound parameters and configuration of identical handpan. The instrument consists of two hemispheres made of 1,2 mm steel. Our innovation consists in the method of tuning. The manipulation and forging of the tongue causes very interesting effect – one tongue produces 2 notes instead of one: main tone+overtone, which is commonly tuned +1 octave.
