Handpan, 56 cm, with 10 notes, one more than standard. Includes C5. D minor Color: Gold Tuned to A4 (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 teach children scales. New, but opened for photography, inspection, and cleaning. 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 (Re). The number below D3 in the center is the actual measured frequency. The range of the sound varies depending on how it is played. The center number is the reference frequency for A4 = 432Hz. This handpan is tuned to A4 = 432Hz. When tuning based solely on frequency, there may be a discrepancy with the actual sound, so tuning is done within a range that sounds natural to the ear.
