I have three Bach records which all sound (to me) our of tune when I play them.
All my other records sound (to me) fine.
It is possible that my record player is out of tune and I just can't tell, except when I listen to Bach? Or have my ears gone wonky?
The record player is 15 years old, and one of those manual ones where you have to take the turn table off and move the elastic band to change speed. I have never changed the stylus. The noise that comes out of it is weighty and clear. I just don't understand why Bach sounds out of tune.
