Handpan, 56 cm, with 12 notes, 3 more than the standard. It's called a mutant. D minor The color is elegant gold. For 12-note handpans, the top two notes sound better on the surrounding rings than in the center. 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 is said to sound gentler and more beautiful, and to have a healing effect. Nowadays, 432Hz instruments are used in Steiner education to let children hear scales. It's new, but it has been opened for photography, inspection, and cleaning. The pitch has been checked, and tuning has been done to the extent possible. 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. Measurements are taken with an Android app, so there may be some error. Please consider them as a reference. The range of the notes varies depending on how you play. When tuning based solely on frequency, there may be a discrepancy with the actual sound. Tuning is done within a range that sounds natural to the ear. Regarding trial play videos: Posting URLs and directing to external sites is prohibited by Mercari guidelines.
