How to Tune Your Guitar: Standard Tuning and Methods Explained

1 Standard Tuning: EADGBE

Standard tuning is the default tuning for guitar, and the vast majority of songs, lessons, and instructional materials assume your guitar is in standard tuning. The six strings, from lowest-pitched (thickest) to highest-pitched (thinnest), are tuned to the notes E - A - D - G - B - E. Understanding these string names and numbers is fundamental to everything you will do on the guitar.

The strings are numbered from thinnest to thickest: the 1st string is the high E (thinnest), and the 6th string is the low E (thickest). This numbering system can be confusing at first because the 1st string is at the bottom when you are looking down at the guitar in playing position. It helps to think of "1st" as "highest-pitched" rather than "top" or "bottom."

A common mnemonic to remember EADGBE from the 6th string to the 1st is "Eddie Ate Dynamite Good Bye Eddie" or "Every Amateur Does Get Better Eventually". Pick whichever one sticks in your memory, or make up your own. Within a few weeks of playing, the string names will become second nature.

Note that the low E (6th string) and the high E (1st string) are the same note, just two octaves apart. If you pluck both together, you will hear how they harmonize. This octave relationship is a useful reference point when tuning by ear, and it will become more meaningful as you learn about tablature and music theory.

2 Using a Clip-On Tuner

A clip-on tuner is the most popular and practical tuning tool for beginners. It clamps onto the headstock of your guitar and detects the pitch of each string through vibrations in the wood, which means it works even in noisy environments where a microphone-based tuner would struggle. Popular models include the Snark SN-5, TC Electronic PolyTune Clip, and Korg Pitchclip.

To use a clip-on tuner, attach it to the headstock and turn it on. Pluck a single string and let it ring. The tuner's display will show the note it detects and indicate whether the string is sharp (too high), flat (too low), or in tune. Most tuners use a needle or LED lights: when the indicator is centered and the screen turns green, the string is in tune.

Start with the 6th string (low E) and work your way to the 1st string (high E). Pluck each string individually, not together. If the tuner shows a note that is completely wrong (for example, it reads "D" when you are trying to tune to "E"), it means the string is very far off. Turn the tuning machine to tighten (raise pitch) or loosen (lower pitch) the string until the tuner shows the correct letter, then fine-tune until the needle is centered.

Always tune up to the target pitch, not down to it. If you overshoot and the string is slightly sharp, loosen it below the target note and then tighten back up. This keeps the tuning gear engaged in one direction and helps the string hold its pitch longer. When tuning, make slow, small adjustments and pluck the string again after each adjustment to check your progress.

3 Tuning with a Smartphone App

If you do not have a clip-on tuner, a smartphone tuning app is an excellent free alternative. Popular apps include GuitarTuna, Fender Tune, and BOSS Tuner. These apps use your phone's microphone to detect the pitch, so they work best in a quiet environment. In a noisy room, the microphone may pick up background sounds and give inaccurate readings.

Most tuning apps are designed specifically for guitar and automatically detect which string you are playing. The interface typically mimics a real tuner with a needle display and color-coded feedback. Green means in tune, red or orange means you need to adjust. Some apps even have an auto-detect mode that listens for each string in sequence and guides you through the process step by step.

One advantage of apps over basic clip-on tuners is that they often include additional features: alternate tunings presets, chord libraries, metronomes, and tone generators. GuitarTuna, for example, includes a game-like interface that makes tuning almost fun for beginners. The downside is that you need to have your phone out and nearby, which can be a distraction during practice.

For best results with an app, hold your phone within a foot or two of the guitar's soundhole (for acoustics) or the amplifier speaker (for electrics). Pluck the string firmly so the app receives a clear signal. If the app is struggling to detect the pitch, try moving to a quieter spot or cupping your hand around the phone's microphone to reduce ambient noise.

4 Tuning by Ear: The 5th-Fret Method

Tuning by ear is a skill that every guitarist should develop over time. While a tuner is more accurate and convenient for daily use, training your ear to recognize pitch relationships deepens your musicianship and comes in handy when technology is not available. The most common ear-tuning method is the 5th-fret method.

The principle is simple: when you press a string at the 5th fret, it produces the same note as the next open string (with one exception). So you can tune each string relative to the one next to it. Start by getting the 6th string (low E) in tune using a tuner, a piano, a tuning fork, or a reference tone. Then use it as the anchor for all other strings.

Step 1: Tune the 6th string (E) to a reference pitch
Step 2: 6th string, 5th fret = 5th string open (A)
Step 3: 5th string, 5th fret = 4th string open (D)
Step 4: 4th string, 5th fret = 3rd string open (G)
Step 5: 3rd string, 4th fret = 2nd string open (B)  ← NOTE: 4th fret!
Step 6: 2nd string, 5th fret = 1st string open (E)

Important: Step 5 uses the 4th fret, not the 5th.
This is because of the interval between G and B strings.

Play both notes simultaneously or in quick alternation and listen for a wavering or beating sound. When two notes are almost but not quite the same pitch, you hear a pulsing effect called "beats." As you bring the strings closer in pitch, the beating slows down. When the beating stops completely and the two notes blend into one smooth tone, the strings are in tune with each other.

The one exception in this method is between the 3rd and 2nd strings: you use the 4th fret of the 3rd string to match the open 2nd string, not the 5th fret. This is because of the way the guitar's standard tuning is constructed. The interval between every other adjacent pair of strings is a perfect fourth (5 semitones), but the interval between G and B is a major third (4 semitones). This quirk is worth memorizing early on.

5 Why Your Guitar Goes Out of Tune

If your guitar seems to go out of tune frequently, you are not doing anything wrong. Guitars are influenced by several physical factors that cause tuning drift. Understanding these factors helps you minimize the problem and know when an out-of-tune guitar is normal versus a sign that something needs repair.

New strings are the number one cause of tuning instability. Fresh strings need to stretch before they stabilize. When you put on a new set, they will go flat repeatedly for the first day or two of playing. You can speed up the break-in process by gently pulling each string away from the fretboard to pre-stretch it, then retuning. Repeat this stretch-and-tune cycle three or four times per string.

Temperature and humidity changes cause the wood in your guitar's neck to expand and contract, which changes the tension on the strings. Moving a guitar from a cold car into a warm room, or playing outdoors on a hot day, will cause tuning drift. Keeping your guitar in its case when not in use and maintaining a consistent room humidity (40-60%) helps minimize this effect.

Worn or low-quality tuning machines can slip, especially on budget guitars. If a tuning machine does not hold its position after you tune, the gear mechanism may be worn or the mounting screws may be loose. Tightening the screw on the tuner button or the mounting screws on the headstock can sometimes fix the issue. If not, tuning machine replacement is relatively inexpensive and straightforward. Nut friction is another common culprit: if the nut slots are not properly lubricated, strings can bind in the grooves and pop out of tune after bending or heavy strumming.

6 Tips for Tuning Stability

Beyond understanding why guitars go out of tune, there are practical steps you can take to keep your guitar in tune longer. These tips are used by professional musicians who cannot afford tuning problems during performances.

Wind your strings properly when changing them. Each string should wrap neatly around the tuning post, with the winds going downward toward the headstock surface. This creates a clean break angle over the nut and ensures the string winds do not overlap or tangle. Aim for 2-3 full wraps on the wound strings (6th-4th) and 3-4 wraps on the plain strings (3rd-1st).

Lubricate the nut slots with a graphite pencil. Simply rub the pencil tip in each nut slot when you change strings. The graphite acts as a dry lubricant that helps strings glide smoothly through the nut, which is especially important if you use a tremolo bar or do a lot of string bending. Some players use specialized nut lubricants like Big Bends Nut Sauce for the same purpose.

• Stretch new strings - pull gently and retune 3-4 times per string
• Tune up to pitch - always approach the target note from below
• Wind strings neatly - no overlapping wraps on the tuning post
• Lubricate the nut - graphite pencil or nut lubricant in each slot
• Check tuning machine tightness - tighten the button screw and mounting screws
• Store properly - in a case or stand, away from temperature extremes
• Change strings regularly - old strings corrode and lose their ability to hold pitch accurately

Tuning is something you will do before every practice session and often during it. As you develop your ear and become familiar with your specific guitar's quirks, tuning becomes a quick, almost automatic part of your routine. Make it a habit to check your tuning every time you pick up the instrument, and you will always sound your best.
