I have an old one-key fife that was made by G. Butler & Sons. It’s in the key of B - I know that this is one of the least used keys for making whistles, but I have no idea if it was ever really used for fifes.
My problem is - its intonation is very good until I get a few notes into the upper register. I’ll talk in terms of a “D” flute or whistle, since that’s what I’m used to - the notes from high F# (if this was a “D” fife) on up get progressively sharper.
I’d like to think that my embrasure isn’t bad enough to make these notes go as sharp as they do (I don’t have this problem when playing a flute). Could it be the position of the cork? I’m quite possibly showing my ignorance here - I’m assuming that B is a strange key for a fife, could it be that the cork just needs to be moved one way or the other (maybe it’s supposed to be a Bb or C fife…)? Would moving the cork help the intonation problem that I’m having?
