Its patented tongue design — the original Vast tongue shape with a signature V-tip — allows each tongue to produce a polyphonic blend of 7, 5, or 4 harmoniously tuned notes. This creates a natural chorus effect that sounds richer than traditional handpans.

The patented body design features a unique system of internal ribs, delivering cleaner sound and allowing more tuned harmonics to shine through. Unlike typical tongue drums, the high frequencies are not absorbed by the body but remain vibrant and bright.
