How to Tune a Guitar: Standard EADGBE Tuning Guide

Standard guitar tuning (EADGBE) means tuning your six strings, from lowest to highest, to the pitches E2–A2–D3–G3–B3–E4 — each a specific, fixed reference pitch that allows you to play with other instruments and recordings. The fastest way to tune as a beginner is with a clip-on chromatic tuner or a free tuner app, which display your string's current pitch and tell you whether to tune up or down. Getting this right before every practice session is the single habit that separates guitarists who develop good ears from those who unknowingly practice with out-of-tune instruments for months.

Standard guitar tuning (EADGBE) means each string is set to a specific pitch: E2, A2, D3, G3, B3, and E4 from the thickest to thinnest string. For most beginners, the fastest and most accurate method is a clip-on chromatic tuner — it reads your string's vibration and tells you exactly how much to tighten or loosen each peg. This guide covers every tuning method available, from electronic tuners to tuning apps, so you can keep your guitar in tune regardless of what tools you have on hand.

The Fastest Method: Clip-On Chromatic Tuner

A clip-on tuner ($10–$25) attaches to your headstock and reads the vibration of the wood — not just the sound in the air — so it works even in noisy rooms. This is the method most guitarists use live and in rehearsal.

Step-by-step: 1. Clip the tuner to your headstock and turn it on 2. Pluck the 6th (thickest) string — the low E 3. Watch the tuner display: turn the tuning peg until the needle centers and the light turns green 4. Repeat for each string in order: A (5th), D (4th), G (3rd), B (2nd), E (1st) 5. Go through all 6 strings a second time — tightening one string slightly loosens adjacent ones

Pro tip: Always tune up to the note, not down. If you overshoot the pitch, drop below it and tune up again. This prevents slippage at the nut.

Recommended tuners: Snark ST-8 (~$12), D'Addario NS Micro (~$18), KLIQ UberTuner (~$22).

Tuning With a Free App

Tuner apps use your phone's microphone to detect pitch. They're accurate in quiet rooms and cost nothing. GuitarTuna (iOS/Android) and Fender Tune are the most popular, each with over 10 million downloads.

Step-by-step: 1. Open the app, select "Standard Tuning" (EADGBE) 2. Hold your phone about 12 inches from the guitar's soundhole or body 3. Pluck one string at a time and watch the display 4. Adjust the tuning peg until the needle/bar centers 5. Avoid tuning near loud music or HVAC noise — the mic picks up everything

Apps work well for practice rooms and home use. For live or rehearsal environments, a clip-on tuner or pedal tuner is more reliable.

Tuning by Ear: The 5th-Fret Method

Once your low E string is in tune (use a reference pitch from a tuning fork, piano, or app), you can tune the remaining strings relative to it.

• 6th string (low E): Your reference pitch — get this from an external source
• 5th string (A): Fret the 6th string at the 5th fret — this note is A. Tune the open 5th string to match
• 4th string (D): Fret the 5th string at the 5th fret — this is D. Tune the open 4th string to match
• 3rd string (G): Fret the 4th string at the 5th fret — this is G. Tune the open 3rd string to match
• 2nd string (B): Fret the 3rd string at the 4th fret (not the 5th) — this is B. Tune the open 2nd string to match
• 1st string (high E): Fret the 2nd string at the 5th fret — this is E. Tune the open 1st string to match

The one exception — 4th fret on the G string for B — catches beginners every time. The interval between G and B is a major third, not a perfect fourth like all the others.

Alternate and Drop Tunings

Standard EADGBE is used in most genres, but you'll encounter others frequently:

• Drop D (DADGBE): Lower the 6th string by one whole step. Instant power chord access; used in rock, metal, and folk
• Open G (DGDGBD): All strings form a G major chord when strummed open; favored in blues and slide guitar
• Half-step down (Eb Ab Db Gb Bb Eb): Every string one semitone lower; easier bending, and used by Jimi Hendrix and Stevie Ray Vaughan
• Full step down (DGCFAD): Popular in metal and hard rock for a heavier tone

For any alternate tuning, a chromatic tuner is essential — it can read any pitch, not just standard notes.

Why Your Guitar Won't Stay in Tune (and How to Fix It)

New strings go out of tune frequently until they're stretched and broken in. Beyond that, these are the most common culprits:

• Worn nut slots: If the string catches or clicks when you tune, the nut slot needs to be widened or lubricated (pencil graphite works temporarily)
• Cheap tuning machines: Budget guitars often come with tuning pegs that slip. An upgrade to locking tuners (~$30–$60) can make a dramatic difference
• Temperature and humidity changes: Wood expands and contracts. A guitar left in a hot car will be out of tune when you return
• Bending strings during tuning: Always fret gently when testing pitch. Pressing too hard sharp the note

New strings: Stretch them immediately after installation. Pull each string away from the fretboard gently (about 1 inch), retune, and repeat 4–5 times per string. Properly stretched new strings hold tune within an hour instead of a full day.

FAQ

How often should I tune my guitar? Tune every single time you pick up the guitar. Temperature changes, humidity shifts, and even sitting untouched overnight can cause strings to drift. It takes 60 seconds with a clip-on tuner and prevents practicing bad intonation.

Why does my guitar sound out of tune even after I tune it? If individual notes sound slightly off even when open strings are correct, your intonation needs adjustment. Intonation is set by moving the saddle position at the bridge — a 15-minute task for a guitar tech that costs $20–$40. A properly intonated guitar plays in tune at every fret, not just open strings.

Can I tune a guitar without any tools? Yes, using the 5th-fret method described above, as long as you have one reference pitch for the low E string. In practice, a free app on your phone is so accessible that "no tools" tuning is mostly a backup skill. Learn both.
