Tuning Forks

How to Use a Tuning Fork
To use a tuning fork, simply hold the base with one hand and gently tap the pronged side against a solid surface, like your knee or a chair. The fork will resonate and create a specific pitch, commonly A (440hz) or E (329.6hz), which you can then match to the string(s) of the guitar that need to be at that pitch.
Why Do Musicians Use a Tuning Fork?
Musicians use tuning forks because they are an accurate way to find the pitch needed to tune your instrument and they do not require a power supply. The sound is also lasting and consistent, even with one hit.
What is the Difference Between Different Tuning Forks?
The main difference between tuning forks is the pitch they are built to resonate at. Tuning forks are commonly made to create an A (440hz) or E (329.6hz) pitch, which is good for guitar. There are a few different styles of tuning forks, but they all function the same way and have a specific pitch they vibrate at.
