No, Peter. You have it wrong.Peter Laban wrote: Which is the usual description Wanderer's uses when he mentions his attempts to play a whistle in tune and he has used it many times in the past in the context of Generation whistles. Your almost exact same choice of words did strike me as at least less original.
If a whistle requires you to push one note especially hard to be in tune, and the very next note needs to be blown especially softly, yes, that whistle can be played in tune. But that's a kind of "breath gymnastics" that many people would not tolerate.
I have not described Generations has requiring breath gymnastics in general. I do not believe, in general, that they do. I'm putting that in big red letters because you seem to keep missing that point.
Some of the specific Generations I have tried, and some specific whistles of other brands, including high end whistles, I have used that phrase to describe, because it was accurate for those whistles. My website makes clear that I can only review the whistle in my hand, and that I'm willing to take a second look at any whistle. I'm aware as anyone that there is variability even within brands, including Generations. It is my opinion, based upon the dozen or so I've tried, that Generations perhaps have more variability than some brands, but I admit it's been some years since I've had a batch of several. You yourself have described the process of going to search for Generations and weeding out about 75% of those at the store to focus on the four good ones you found.
