It's not about apples that we eat, anons.
It's about Apple products. If not made in China, prices would rise. So build factories and make stuff here, POTUS is saying.
Kek. We're 'zactly like you. Same here.
No, you're super-Elite. This is cool. Kek.
No that is false.
Well-tempered tuning was invented in the late 1500s-early 1600s. Bach was an exponent of the "new" tuning system which allowed a musician to play (a keyboard instrument) in any key and the slight error of the comma of pythagoras is distributed across the entire chromatic scale. So no one key sounds beautifully in tune like a bowed string instrument or voice can play.
Orchestras tuned up to A=432Hz for a long time. The standard tuning went to A=440 during the early part of the 20th century IIRC. The standard pitch for tuning has gone up and up and up over the centuries. You cannot tune medieval instruments to today's concert pitch because they were not designed to support that much tension. Musicologists have been able to figure out that the standard tuning has continually gotten higher and higher over the centuries.
