Make another sharp bend in the string on the outside of the tuning post.

Turn the tuning key counter clockwise while applying light pressure to the string on the inside of the post.

Wrapping the string around the post will help the string stay in-tune longer.

If the wraps of the string around the post start to roll over the top of the post, hold them down while still turning the post.

Continue turning the post until at least 2 full wraps of the string have been made around the post.
