The resonators Today, most of the gourds come from the southern part of the state of Maharashtra, reputed for its cultivation of the plant. Once selected, the fruit will be hollowed out and dried. For hollowing it, there are two openings made: one on top and the other at the base of the fruit. The upper opening will then be covered by a wooden crown meant not only to protect the fragility of the gourd when it will be attached beneath the tube but also to reduce vibratory phenomena that could damage the resonance of the instrument. The lower opening, which connects the cavity with the exterior, lets the resonator get the best acoustic effect.
