Meinl Sonic Energy Sensory Handpans are elaborately handmade one at a time. They produce clear and pure notes when struck by the hand. The tone is pleasing, soothing, and relaxing and can be used in a variety of settings both for performance and therapy. Stainless steel handpans are easy to play, and feature a long sustain and a big dynamic range. Each one is tuned with one center note and additional notes around allowing the player to work within a musical scale both as a solo instrumentalist and with a group. These handpans include two soundholes: One, that faces the player, and one, that faces the audience. Please note: Natural color variations may occur due to the individual heating process each instrument undergoes during manufacturing.
