We had two handmade wooden whistles given to us for wedding presents, regretably stolen from our car some years ago. Two different woods, they had different tones and actions. Oddly enough the denser wood was a lighter tone, and the pale, lightweight wood was deeper. They needed considerable playing in, but were very sweet toned and warm to play. They had a sound similar to a wooden flute, which is much rounder and warmer than the metal ones.
