摘要

The instrument has neck (12) fixed on the body in a removable manner. The neck has a heel (14) with two notches (21, 22) for receiving two pins (10, 11) that are integrated to a main beam fixed on the body, so that the neck is fixed on the body by tension of strings. Lateral units are fixed on a resonance case (2) of the body using hinges, so that the units are folded perpendicular to the body.
