I had never given any thought to A above middle C being fixed at 440Hz until I stumbled across this:

440Hz seems like such an easy number to work with, along with 110, 220, 880, 1760 etc., but in today's digital age, putting C at 256 (a binary number) has a certain perfection to it. Have these changes created issues over the centuries and what do we do when nontunable instruments of antiquity are played in concert with modern instruments? I don't know if an oboe is tunable, but the article does mention that it was or is used as the standard by which to tune the orchestra.
