I tried playing my whistle (Sindt in D) next to an electric tuner. It seems like I’m about 20 cents (is that the right terminology) sharp on every note, except A, which is somewhat close, unless I play very softly.
Is this typical? Is there a way to tune this thing? is 440 Hz the standard tuning?
Thanks in advance for helping with my ignorance here. I know I’ve read about whistles being typically sharp but I’m not sure whether it’s operator error or comes with the territory.
