SUMMARY

The discussion centers on the tuning process of a piano string in relation to the beats heard when combining a tuning fork with the piano note. Initially, the tuner hears 2 beats per second, indicating a significant frequency difference. After tightening the string, the beats reduce to 1 per second, suggesting the frequencies are closer. The conclusion is that the tuner should loosen the string to achieve the correct pitch, as further tightening would increase the frequency difference and the number of beats.

Suppose a piano tuner hears 2 beats per second when listening to the combined sound from her tuning fork and the piano note being tuned. After slightly tightening the string, she hears 1 beat per second. Should she loosen or shoud she further tighten the string?

I believe the answer is to loosen the string, but I'm not sure...

Thanks in advance!

Well, the beats occur because the notes are of different frequencies, right? As their frequencies get closer, do the number of beats per second increase or decrease? How many beats per second will you hear if you play two notes of the same frequency?
