ond when listening to the combined sound
from his tuning fork and the piano note being

the frequency of the string is 5 hz below the
correct freguency.
2. the string should be tightened because
the frequency of the string is 5 hz above the
correct frequency.
3. the string should be loosened because
the frequency of the string is 5 hz above the
correct frequency.
