It`s rather difficult to say clearly to which family of musical instruments GUDA belongs to. The instrument itself is quite young, and it does not stop its process of transformation in its sounding.

Technologically GUDA consists of two connected metal hemispheres made of stainless steel sheet 1.2 mm thick. The earlier production of GUDA models were made of high-carbon steel.

In the center of the upper hemisphere is positioned 8 cm opening which serves to increase the sound volume.

Semicircular reeds, located on the upper hemisphere, serve as the source of vibrations and sound. The lower hemisphere has no openings and serves to reinforce the resonance. While playing the GUDA you can find an interesting acoustic effect – one reed of the instrument produces two notes. In addition to the main tone, the reed performs additional sound one octave above. Thus, when you are playing the GUDA, to the characteristic “belfry” sounding of reed instrument, a kind of “steel pan” overtone is added. As a consequence, GUDA performs more complex timbre, as well as the volumetric and brighter sound. Also another interesting point is the use of harmonics while playing, which are extracted when struck just below the melodic lobe.
