Beginning technicians are often advised to initially set F3-A3 to 7 beats per second (bps). Mathematically F3-A3 = 6.9 bps in equal temperament so it's a good guess.
After using the skeleton or contiguous M3's also known as Jack's Stack, we can refine F3-A3 to be more what the piano needs, but 7 bps is a good starting point.
The question is, how do we know what 7 bps is, or how accurate we were when we set our own F3-A3?
IPTS uses FREE powerful band pass filter technology to answer this and many other tuning questions.
Watch the video below and learn how you can finally know for sure whether your F3-A3 is 7 bps or not!
Band pass filters are quickly becoming the #1 way to learn piano tuning.
If you are interested in getting this kind of feedback for your own tunings, we have a new course that is one quarter the price of our private lessons and you get the same kind of powerful band pass filter feedback.
