If a vibrating anchored at each end is shortened in length with tension remaining constant one would notice an apparent pitch increase or decrease?

Answer 1

pitch increased

Answer 2

If a vibrating string anchored at each end is shortened, the frequency of vibration will increase, leading to a higher pitch. This is because the shorter length results in shorter wavelengths and higher frequencies. On the other hand, if the tension is increased while keeping the length constant, the pitch will also increase due to higher tension causing higher frequencies of vibration.
