Standard Tuning
E A D G B E · 440 Hz
How to Use This Tuner
Standard guitar tuning for a six-string instrument is E A D G B E, from the lowest sounding string to the highest. In scientific pitch notation this corresponds to E2, A2, D3, G3, B3, E4 — all based on concert standard A = 440 Hz.
Start with the 6th string (low E). Tap it above to hear the reference tone. Play your open 6th string and compare carefully.
If your note sounds lower than the reference, tighten the tuning peg slightly. If it sounds higher, loosen gently, then bring it back up.
Always approach the correct pitch from below for better tuning stability.
Continue in order: 6th, 5th, 4th, 3rd, 2nd, 1st. After all six strings, play a simple open chord to confirm balance.
Tuning with a Tuning Fork
A tuning fork is a simple mechanical tool that vibrates at a fixed frequency — most commonly A = 440 Hz. Strike the fork gently against a firm surface and listen to the pitch. Match your open 5th string (A) to the fork. Adjust slowly until both sounds align.
Once your 5th string is accurate, use it as your anchor. You may tune the remaining strings using string-to-string tuning or harmonics. This method works for classical, acoustic, electric, and bass guitar.
String-to-String Tuning by Ear
Tuning by ear is an essential skill in any serious guitar course. This method lets you tune the guitar relative to itself — even without a tuning fork or piano. Note that small inaccuracies may accumulate, so a reference pitch is always recommended as a starting point.
Play the 6th string at the 5th fret and tune the open 5th string to match.
Play the 5th string at the 5th fret and tune the open 4th string to match.
Play the 4th string at the 5th fret and tune the open 3rd string to match.
Play the 3rd string at the 4th fret and tune the open 2nd string to match.
Play the 2nd string at the 5th fret and tune the open 1st string to match.
When comparing pitches, listen for the pulsing or "beating" between the two notes. As the notes approach alignment, the beating slows. When it disappears, the pitches match.
Tuning with Harmonics
Tuning with harmonics is often more precise than fretted string-to-string tuning because you avoid finger pressure altering pitch. Both strings ring clearly, making pitch comparison easier.
To produce a natural harmonic, lightly touch the string directly above the fret wire, then release immediately after playing the note so it rings clearly.
Match the 6th string 5th-fret harmonic to the 5th string 7th-fret harmonic.
Match the 5th string 5th-fret harmonic to the 4th string 7th-fret harmonic.
Match the 4th string 5th-fret harmonic to the 3rd string 7th-fret harmonic.
Match the 6th string 7th-fret harmonic to the open 2nd string.
Match the 5th string 7th-fret harmonic to the open 1st string.
Using a Reference Instrument
Another reliable way to tune a guitar is to use an external instrument such as a piano or keyboard. If the piano is well tuned, you can match each open string directly to its corresponding note. Many players use the 5th string A as their anchor — once correct, avoid adjusting it again.
Piano or Keyboard
Match each open string directly to its corresponding note. Works well when the piano is reliably in tune.
Recorded Reference
Use a clear single pitch rather than a full song. Mixed recordings can mask pitch comparison.
Digital Tuner
Fast and convenient for on-stage use, though tuning by ear builds stronger pitch recognition over time.
Tuning Fork
Establishes a single anchor pitch at A 440 Hz, then build outward from your 5th string.
By combining this tuner with ear training methods, you develop both accuracy and independence. Over time, tuning becomes faster, more precise, and an integral part of your daily guitar practice routine.
