Good Day, has anyone experienced a change in pitch due to a fluctuation in temperature or humidity, could either of these cause a change? My wife and I sat down to play some tunes, after she had tund her stringed instrument with an electronic tuner, we noticed that the concertina was noticably flat across all notes. I got my other tina and noticed that it was also a bit flat. One of the instruments is new and the other is an older instrument. Over a 48 hour period we had a significant change in temp and humidity. Any thoughts?
Thanks
Mark
