Guitar playing is an art form that requires a combination of talent, skill, and dedication. One of the most important aspects of playing the guitar is getting the right sound. The sound of the guitar is influenced by many factors, including the type of guitar, the strings, and the way the strings are played. In this article, we will explore the concept of intonation, what it is, and how it affects the sound of the guitar. We will also look at some tips and techniques to help you achieve good intonation when playing the guitar.
What is Intonation on the Guitar?
Intonation refers to the accuracy of the musical pitch that is produced by a stringed instrument such as the guitar. When playing the guitar, intonation refers to the ability of the strings to produce notes that are in tune with each other. When a guitar is properly intonated, the notes played on each string will sound in tune with each other and with the chords that are being played.
How Does Intonation Affect the Sound of the Guitar?
Good intonation is essential for producing a good sound on the guitar. If a guitar is not intonated properly, the notes played on each string will not sound in tune with each other, and the chords will not sound harmonious. This can make the guitar sound out of tune and can be frustrating for the player and listener alike. Good intonation is also important for playing in different keys, as the same chords will sound different when played in different keys.
What is guitar intonation?
Intonation refers to the accuracy of the pitch of each string on a guitar. When a guitar is properly intonated, the notes played on each string will be in tune with one another. This is important for creating a pleasing sound and for playing in harmony with other instruments.
Why is guitar intonation important?
Proper intonation is essential for achieving a clear and accurate sound on your guitar. Without proper intonation, notes played on different strings may be out of tune with one another, resulting in a discordant or “off” sound. Additionally, poor intonation can make it difficult to play in harmony with other instruments or to perform in a group setting.
How to check guitar intonation
To check the intonation on your guitar, you’ll need an electronic tuner and a guitar that is already in tune. Start by playing the open string and then play the 12th fret harmonic of the string. The two notes should be the same. If the fretted note is flat or sharp compared to the harmonic, then the intonation needs to be adjusted.
Another way to check the intonation is by playing a chord and then playing the individual notes of the chord. The notes should be in tune with one another. If they are not, the intonation needs to be adjusted.
How to adjust guitar intonation
Guitar intonation is typically adjusted by adjusting the position of the saddle on the guitar’s bridge. On most electric guitars, the saddle is adjusted by turning a small screw. On acoustic guitars, the saddle may need to be filed down or shimmed to adjust the intonation.
It is recommended to seek the help of a professional guitar technician or luthier when adjusting intonation. However, if you are familiar with your instrument and feel comfortable making adjustments, you can try the following steps:
Determine which string is out of tune.
Locate the saddle for that string on the guitar’s bridge.
Adjust the position of the saddle by turning the screw or filing down the saddle.
Play the string and check the intonation with a tuner.
Repeat the process for each string that needs adjustment.
Tips for maintaining guitar intonation
Keep your guitar in tune. Regularly tuning your guitar will help maintain proper intonation.
Use fresh strings. Old strings can stretch and lose their tension, affecting intonation.
Avoid extreme temperature and humidity changes. These can cause wood to expand and contract, affecting the guitar’s intonation.
Be gentle with your guitar. Dropping or bumping your guitar can cause the bridge or saddle to shift, affecting intonation.
Have your guitar professionally serviced. A qualified technician can check and adjust your guitar’s intonation as well as address any other issues that may be affecting your instrument’s performance.
Common intonation issues
One common intonation issue is that the strings are sharp at the higher frets. This can be caused by the string stretching as it is fretted, pulling the pitch of the string sharp. This can be corrected by adjusting the saddle position, moving it closer to the neck.
Another issue is that the strings are flat at the higher frets. This can be caused by the string being too short or the saddle being too far from the neck. This can be corrected by adjusting the saddle position, moving it further away from the neck.
A third issue is that the intonation is inconsistent across the different strings. This can be caused by an issue with the guitar’s nut or by the guitar not being properly set up. It is recommended to have a professional guitar technician or luthier check the guitar and make any necessary adjustments.
How to intonate an electric guitar
Intonating an electric guitar is a bit different than intonating an acoustic guitar. Electric guitars have a bridge with individual saddles for each string. To intonate an electric guitar, you will need to adjust the position of each saddle for each string.
Start by tuning your guitar to standard tuning.
Play the harmonic on the 12th fret of each string and compare it to the fretted note on the same string.
If the fretted note is sharp, move the saddle closer to the neck. If the fretted note is flat, move the saddle away from the neck.
Use an electronic tuner to check the intonation after each adjustment.
Repeat this process for each string.
How to intonate an acoustic guitar
Intonating an acoustic guitar is a bit different than intonating an electric guitar. Acoustic guitars have a fixed saddle that cannot be adjusted. To intonate an acoustic guitar, you will need to file down or shim the saddle.
Start by tuning your guitar to standard tuning.
Play the harmonic on the 12th fret of each string and compare it to the fretted note on the same string.
If the fretted note is sharp, file down the front of the saddle. If the fretted note is flat, file down the back of the saddle.
Use an electronic tuner to check the intonation after each adjustment.
Repeat this process for each string.
Conclusion
Guitar intonation is a critical aspect of achieving a clear and accurate sound on your instrument. By understanding the basics of intonation, the common issues and the techniques of checking and adjusting intonation, guitar players of all levels can improve their playing and achieve a higher level of musicianship. Remember that it is always recommended to seek the help of a professional guitar technician or luthier when adjusting intonation.
