Freeman Tweaked Bluebird D Whistle - NEW 2013 Model Similar in sound to a Freeman Blackbird (pure and sweet), yet easier for a beginner to play, since it does not require the careful breath-control needed to play a Blackbird. The newer model features an attractive brass ring around the base of the mouthpiece to improve durability and prevent cracking when the whistle is tuned. Jerry Freeman expertly tweaks mass-produced whistles to improve quality and produce a clean playing, beautiful sounding, nicely in-tune instrument that's well balanced throughout both registers. Elimates the uneven register issues that show up in mass-produced whistles. High notes stay sweet and pure rather than going shrill. Jerry Freeman on his Bluebird whistles: "...The result is a really (I mean REALLY) great whistle. I'm very excited about this. It is pure and birdlike, as I had expected, but a different whistle from a Blackbird. (For one thing, it's easier to play, and though it's voiced purer/sweeter than even a pre-1980's Generation, it still has some of the Generation character.)"
