Handmade wind chime with perfect tuning

The Zaphir Sunray Chime Salmon Red is a wind chime with eight tones in Sunray (summer) tuning. The tones are produced by high-quality piano strings, which are also soldered to a solid metal base and then tuned to the tenth of a millimeter. This is how you get the perfect chords that allow the harmonics to play together when the centered bead makes a circular or random motion. The dimensions of the resonator correspond to the concept of natural equilibrium associated with Leonardo Da Vinci's golden ratio, a crucial reason for the quality of acoustic waves. The resonance tube is made of thin layers of calendered cellulose. The spiral winding of the layers creates a thin cylinder that guarantees a crystal-clear sound.
