Handpan, 56 cm, with 12 notes, three more than the standard. It's called a Mutant. D minor. The color is elegant gold. Tuned to A4 (the note La) = 432Hz. Modern instruments are all tuned to A4 = 440Hz, but before 1939, classical music was tuned to 432Hz. Mozart and Vivaldi composed in 432Hz. 432Hz tuning sounds gentler and more beautiful, and has a healing effect. Nowadays, Steiner education uses 432Hz instruments to let children listen to scales. It's new, but it has been opened for photography, inspection, and cleaning. The pitch has been checked and tuned as much as possible. You won't need to tune it after purchase. The last image shows the frequencies for each position. The center is the base note, starting with D3 (the note Re). The numbers below D3 in the center are the actual measured frequencies. Since it's measured with an Android app, there may be some error, so please consider it as a reference. The range of the sound varies depending on how you play. When tuning based on frequency alone, the actual sound may feel off, so I've tuned it within a range that sounds natural to the ear.
