EVERYTHING A WHISTLE SHOULD BE! Flawless workmanship with precision like a Swiss watch. Just the right amount of breath, just the right amount of chiff, easily glides through both octaves. Comfortable to play. Physically heavy on the top but this does not impair playing in any way - just something to get used to. I love the sound of brass whistles and this one is amazing! Love it. Love it. Love it!
