If you’re wondering how to tune a mandolin, you’ve come to the right place! As a mandolin player, I know how important it is to have the instrument in perfect pitch. Whether you’re a beginner or a more experienced player, tuning your mandolin is a crucial part of achieving the best sound. In this guide, I’ll show you the various methods for tuning your mandolin and achieving perfect pitch.

Parts of a Mandolin

Mandolins have four main components: the body, the neck, the headstock, and the strings. The body is the largest part and is made of wood or laminate. It houses the strings and gives the mandolin its shape. The neck is attached to the body and is typically made of maple or mahogany. The headstock connects the strings to the body and contains the tuning keys. The strings are usually made of metal or nylon and are stretched from the headstock to the body.

Tuning the Mandolin by Ear

Tuning The Mandolin By Ear

In order to tune a mandolin by ear, it is important to be familiar with the notes of the strings. The mandolin has four strings in the standard tuning of G-D-A-E. To help with tuning, play each string individually, starting with the highest string (E) and working down to the lowest string (G).

String Note
E High E
G Low G

Once you have identified the notes of each string, use a pitch pipe, tuning fork, or digital tuner to help you tune each string to the correct pitch. The E string should be tuned to the highest pitch, followed by the A string, the D string, and finally the G string. Once all four strings are tuned to the correct pitch, you can check the intonation (accuracy of the string notes) of the mandolin by playing a few chords.

If the notes of the chords sound slightly out of tune, you may need to adjust the bridge of the mandolin slightly. This can be done by loosening the strings and moving the bridge to the correct position. Once the bridge is in the correct place, retune the strings and check the intonation again.

Tuning the mandolin to the correct pitch and intonation is essential for playing the instrument correctly. With practice, you will be able to tune the mandolin by ear with ease.

Tune the G String

Tune the G string of the mandolin by pressing the string to the third fret. The note at the third fret should match the open G string. If the notes are not in tune, use the tuning pegs at the head of the mandolin to adjust the tuning. Turn the tuning peg clockwise to sharpen the string and counterclockwise to flatten the string. Keep adjusting the tuning peg until the notes match.

Tune the D String

Step Instructions
1 Using a tuning key, turn the tuning peg of the D string until the pitch matches that of the 4th fret of the G string.
2 Check the open D string with an electronic tuner, or pluck the D string and the 4th fret of the G string together and adjust the D string until they match.
3 Repeat the process until the tuning peg of the D string is tight and the pitch of the open D string matches the 4th fret of the G string.

Tune the A String

  1. Place a tuner on the peg head of the A string. It should read A.
  2. Pluck the A string and adjust the tuning peg so that the tuner reads A.
  3. Repeat this process until the tuner reads A.
  4. Check the sound of the A string against the other strings. Make sure that the A string is in tune with the other strings.
  5. Repeat the process until the A string is in tune with the other strings.

Tune the E String

String Note Fret
E E 12
A A 5
D D 0
G G 7

Begin tuning the mandolin by plucking the E string. Adjust the tuning peg until the note sounds an E when fretted at the 12th fret. Make sure to turn the peg in the correct direction, as turning it the wrong way can break the string. To check the tuning, play the note on the 12th fret again. If it is still out of tune, adjust the peg until it is in tune.

Tuning the Mandolin with a Tuner

  1. Clip a tuner onto the headstock of the mandolin.
  2. Turn the machine heads (tuning pegs) until the tuner indicates that the string is in tune.
  3. Repeat for all four strings.

It is important to ensure that the strings are in tune with each other. To do this, pluck two strings together and adjust the tuning pegs until the tuner indicates that they are in tune with each other. Make small adjustments to the tuning pegs to get the strings in tune with each other.

Attach the Tuner to the Mandolin

Tools Instructions
Tuner Clip the tuner onto the headstock of the mandolin.
String Place the tuner’s microphone near the string you want to tune.

Clip the tuner onto the headstock of the mandolin. Place the tuner’s microphone near the string you want to tune. The tuner will detect the string’s vibration and display the note that the string is playing. Adjust the string’s tuning key until the tuner displays the desired note. Repeat this process with each string on the mandolin.

Common Tunings for the Mandolin

Common Tunings For The Mandolin

Tuning Note
GDAE G, D, A, E (low to high)
CGDA C, G, D, A (low to high)
AAEE A, A, E, E (low to high)

Mandolin tuning is the process of adjusting the strings on the instrument to create the desired sound. The four strings of a mandolin are usually tuned in one of three common tunings: GDAE, CGDA, or AAEE.

The most commonly used tuning is GDAE, which is also called the “standard” tuning. The GDAE tuning is the most popular tuning for the mandolin and is used in many styles of music, including bluegrass, Irish, and classical. The notes of this tuning are G, D, A, and E (low to high).

The CGDA tuning is also known as “Celtic” tuning, as it is often used in Celtic music. The notes of this tuning are C, G, D, and A (low to high).

The AAEE tuning is also known as “double-stop” tuning, as it is often used for playing double stops (two notes simultaneously). The notes of this tuning are A, A, E, and E (low to high).

Tips for Maintaining the Mandolin’s Tune

Tips For Maintaining The Mandolin'S Tune

Ensure the strings are securely fastened to the tuning pegs. Always use the same tuning for each string when tuning the mandolin. If a string breaks, replace it with a string of the same size and gauge. Clean the strings with a soft cloth to remove dirt and oil buildup. Ensure the bridge is in the proper position and securely fastened to the soundboard. Check the nut slots for wear and replace if necessary. Inspect the frets for any signs of wear and replace if needed. Have the mandolin professionally set up if it is more than a few years old. Ensure the mandolin is kept in a dry, temperature controlled environment. Store the mandolin in its case when not in use. Have the mandolin serviced periodically to ensure all parts are in good working order.


If your mandolin is not producing the desired sound, the first step is to check the bridge. Make sure it is correctly placed and firmly secured at the base of the instrument. Ensure that the strings are correctly attached to the bridge and the tailpiece. If the strings are not properly secured, they will not resonate properly.

You should also check the nut and the tuning pegs. Make sure they are secured and that the pegs move freely. If they are loose, they will require adjustment.

If the strings are correctly secured and the nut and tuning pegs are in proper position, it is likely an issue with the strings. Strings can become worn over time and need to be replaced. Check each string individually, and if they are frayed or worn, they will need to be replaced.

If the strings are all in good condition, you may need to adjust the truss rod. This is a rod that runs along the neck of the mandolin and can be adjusted to adjust the action of the strings. If the truss rod is too loose, the strings will not be able to vibrate properly and will result in poor sound quality.

Finally, if the problem persists, you may need to take the mandolin to a professional for a more thorough inspection. The professional will be able to identify the source of the problem and provide a solution.

Safety Considerations

  • Ensure strings are not too tight, as this can cause them to snap or damage the neck.
  • Always wear gloves when tuning or handling strings to avoid any injury.
  • Be aware of your surroundings, as the mandolin strings can cause injury or damage when being tuned.
  • Be mindful of the volume of the mandolin, as it may be loud enough to cause hearing damage.
  • Be aware of any pets or children in the area, as strings can cause injury if mishandled.
