MATERIALS: Nanmu Bamboo The sound is deep, with rich overtones and long resonance. It is primarily a musical instrument, with eight metal rods soldered to the bottom metal plate using silver, each of which represents a different tone. According to different metal rods, different tonality is formed, and the emotional colors reflected are also different. Due to its natural and elegant design, it can also be a work of art for home decoration. hluru's precise tuning technology enables it to create a clear tone with overtones. At the same time, we innovatively designed 2 different wind swings that can be replaced according to the scene, which can be used for hand-cranking and suspension. We are applying for patent protection for this design. Tone: C Major Chord、Am Major Chord、Dm Major Chord、G Major Chord
