Carlos Gould · Answer 1

Loosen the string

Explanation:

The beats per second determines the frequency, that is to say, the higher the beats per second, the higher the frequency and hence more pitch and less loudness. the beat frequency depends on the difference between the frequency of tuning fork and note. The piano tuner should loosen the string and go for fewer beats per second
