Handpan, 56 cm, with 12 notes, three more than the standard. It's called a Mutant. D Minor Color: Bronze 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, Steiner education uses 432Hz instruments to let children listen to scales. It's new, but has been opened for photography, inspection, and cleaning. The pitch has been checked and tuned as much as 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 use it as a reference. The range of the notes varies depending on how you play. When tuning based on frequency alone, there may be a sense of incongruity with the actual sound, so I've tuned it within a range that sounds natural to the ear.
