A colleague posed a very interesting question:
“I am looking for any music/music math wizard help me figure this out. If I am moving the pitch of a song up by 50 cents (a quarter step?) What frequency is A instead of 440?”
Sounded like the kind of math challenge I like:
The answer is 452.893Hz

To test and confirm that it’s calculating properly, this is upĀ 100 cents making G# 440
This is down 100 cents making A# 440
