Abstract

This invention provides a triangular oblique composite support tuning bass erhu, addressing the technical problem that existing erhu family instruments lack suitable bass and contrabass instruments for use in folk orchestras, thus failing to meet the artistic expression needs of folk music. It features a soundbox, a neck at the top, a headstock at the top, an inner tuning peg and an outer tuning peg, with strings attached to both pegs. One end of each string is rotatably connected to the inner and outer tuning pegs, and the strings are located on the outside of the soundbox. A bridge is positioned between the strings and the soundbox. The tuning support is triangular in structure, comprising two left and right supports that form a triangle with the front panel. The support positions of the tuning support, the front panel, and the rear panel form a triangular support, and the two supports divide the soundbox into multiple irregularly shaped small resonating cavities. This invention can be widely applied to bass erhu.
