How do I tune up/down a guitar string?

Following the indications provided by our online guitar tuner will involve playing with your guitar pegs in order to tune your instrument. To adjust a guitar's tuning pegs for the purpose of tuning a string either up or down, first identify the peg associated with the string you wish to tune. Grasp the peg firmly and turn it after or while plucking the corresponding string to adjust its pitch. If our online guitar tuner tells you that the string needs to be tuned up to a higher pitch, turn the peg counterclockwise to tighten it. Conversely, if the string must be lowered in pitch, turn the peg clockwise to loosen the string. Please remember that important to make these adjustments gradually and cautiously! Turning the peg in small increments while continually checking the tuner's reading is crucial to avoid overshooting the desired note and, in the worst case, breaking your string. Always use a reliable tuner, like our standard online guitar tuner on OnlineTuner.org, to verify that you have reached the precise pitch before moving on to the next string.

What are the 6 strings of a standard guitar tuning?

A standard six-string guitar is tuned from the thickest string - also the lowest in pitch - to the thinnest string - which is the highest in pitch - as follows:

E2 - 6th string (lowest): This is the thickest string and plays the lowest note on a standard-tuned guitar. In standard tuning, it's tuned to E2. Its frequency is approximately 82.41 Hz.

A2 - 5th string: This string is tuned to A2, and its frequency is approximately 110.00 Hz.

D3 - 4th string: This string is tuned to D3, and its frequency is approximately 146.83 Hz.

G3 - 3rd string: This string is tuned to G3, and its frequency is approximately 196.00 Hz.

B3 - 2nd string: This string is tuned to B3, and its frequency is approximately 246.94 Hz.

E4 - 1st string (highest): This is the thinnest string and plays the highest note on a standard guitar in standard tuning. It's tuned to E4, and its frequency is approximately 329.63 Hz.

It's important to note that these frequencies and notes are for the standard tuning of a guitar (E A D G B e). This online guitar tuner is designed to provide you with all the necessary information and guidance to tune your guitar to a standard tuning. Besides, the frequencies listed above are computed for a standard value of A4 = 440 Hz. You may want to change that value to best suit your guitar tuning requirements. There are also many alternate tunings that musicians use, which will use different notes on different strings to allow for specific techniques or playing styles.

Understand our online guitar tuner's settings

The present online guitar tuner, provided to you by OnlineTuner.org, is designed to suit novice as well as experimented musician's needs. It offers an accurate, robust and versatile tuning experience that can be customized to a user's specific requirements. You can access each of these settings directly on our online guitar tuner, or by clicking on ā€œAdvanced settingsā€.

Set the A4 value of our online guitar tuner

One of the most crucial settings to consider when using our online guitar tuner is the adjustable frequency of the A4 note. This setting serves as the foundational pitch from which all other notes are calculated. While the default is often set to the international standard of A=440 Hz, many musicians have strong preferences for alternative frequencies such as A=432 Hz or A=442 Hz. The ability to adjust this foundational pitch makes our online guitar tuner flexible enough to accommodate musicians who play in various tuning systems, whether they be historical temperaments or modern experimental tunings.

Set the sensitivity of our online guitar tuner

Another pivotal feature of our online guitar tuner is the sensitivity setting, which can be altered to suit the specific environment or instrument in use. You can adjut the sensitivity of our online guitar tuner through the algorithm's probability threshold. By adjusting this, users can control how many notes the tuner will detect and how accurately it will do so. For musicians who require ultra-precise tuning, or that are using specific sound effects on their guitars, this setting can be extremely helpful.

Using our online guitar tuner in challenging environments

Further, the noise gate setting of our online guitar tuner stands as a strong ally for those tuning in acoustically challenging environments. Whether you're in a room with an air conditioner humming in the background or in a rehearsal space with other musicians, the noise gate allows you to set a threshold below which sounds will be ignored by our online guitar tuner tuner. This ensures that only the sound of your instrument is picked up and analyzed, increasing the tuner’s accuracy.

Meter tuner vs Slider tuner

This last setting is just a matter of taste, but you can choose whether you prefer to use our Meter tuner or rather our Slider tuner. To alternate between one and the other, just click on the "Display the slider tuner" switch of our online guitar tuner.
