Answer 1

Becomes lower that is the answer

Answer 2

When you loosen a tuning key, the pitch of the corresponding open string becomes lower.

Tuning keys, also known as tuners or machine heads, are used to adjust the tension of the strings on a musical instrument, such as a guitar or violin. When you turn a tuning key clockwise, you increase the tension of the string, which raises the pitch of the open string. Conversely, when you turn a tuning key counterclockwise, you decrease the tension of the string, which lowers the pitch of the open string. Therefore, if you loosen a tuning key, the pitch of the corresponding open string will become lower.
