How to Measure the Frequency of Guitar Strings

Guitar strings emit frequencies that can be measured using special instruments. The frequency of a pitch determines how high or low the pitch will sound. Guitar strings can be measured just like any other frequency. Using a digital tuner, you can quickly determine the pitch of a string with the readout on the tuner's display. Frequency is measured in hertz and tells you how many times a vibration occurs in a single second.

Step 1 Turn the digital tuner on and set it to the mode that allows you to identify pitches. Generally, this is the default mode and is listed as "Main" or "Tune" on most tuners.

Step 2 Pluck the guitar string as you would normally play it. Hold the pick between your thumb and index finger and use the tip to flick the string. 

Step 3 Identify the number on the readout of your digital display. It will be a three or four digit number and a letter name. This number tells you how many times per second the string is vibrating and is also your frequency in hertz. The letter tells you the name of the pitch. For instance, if you play an A that is perfectly in tune, it will read "440hz A."
