Complete Guitar Tuning Guide
Standard Guitar Tuning (EADGBE)
Standard tuning is the most common tuning for six-string guitars. From the thickest (lowest) string to the thinnest (highest), the strings are tuned to E, A, D, G, B, E. This tuning provides a balance of playability and range that works well for most musical genres.
Here's a detailed breakdown of each string in standard tuning:
- E (6th string, lowest): E2 (82.41 Hz) - The lowest note in standard tuning, providing deep bass tones
- A (5th string): A2 (110.00 Hz) - Perfect fourth above the 6th string
- D (4th string): D3 (146.83 Hz) - Perfect fourth above the 5th string
- G (3rd string): G3 (196.00 Hz) - Perfect fourth above the 4th string
- B (2nd string): B3 (246.94 Hz) - Major third above the 3rd string (the only exception to perfect fourth intervals)
- E (1st string, highest): E4 (329.63 Hz) - Perfect fourth above the 2nd string, and an octave higher than the 6th string
Alternative Guitar Tunings
While standard tuning is the most common, guitarists often explore alternative tunings to create different sounds, make certain chord shapes easier to play, or access different tonal possibilities. Here are some popular alternative tunings:
Drop D Tuning
D - A - D - G - B - E
Drop D is one of the most popular alternative tunings, especially in rock and metal music. It involves lowering only the lowest string (6th string) from E down to D. This allows for easy power chords with a single finger and creates a heavier sound.
Half Step Down Tuning
Eb - Ab - Db - Gb - Bb - Eb
Used by many rock bands including Guns N' Roses and Jimi Hendrix, this tuning lowers every string by one half-step (or one semitone). It creates a slightly looser feel and darker tone while maintaining the same relationships between strings.
Open G Tuning
D - G - D - G - B - D
Made famous by Keith Richards of The Rolling Stones, Open G tuning creates a G major chord when all strings are played open. It's achieved by tuning to D-G-D-G-B-D from low to high.

- Start with the lowest string (6th string, E) and work your way up to the highest (1st string, E).

Common Guitar Tuning Questions
How often should I tune my guitar?
Ideally, you should check your guitar's tuning every time you play. Factors like temperature, humidity, string age, and playing style can all affect tuning stability. New strings typically require more frequent tuning until they stretch and settle.
Why do guitars go out of tune?
Guitars go out of tune for many reasons: temperature and humidity changes cause the wood to expand or contract, new strings stretch over time, frequent bending or aggressive playing can loosen tuning pegs, and even the quality of the instrument's hardware affects tuning stability.
Can I tune a classical or electric guitar?
Absolutely! Our tuner works with any type of guitar - acoustic, electric, or classical.
Can I use this tuner for other string instruments?
Theoretically, yes! While our online tuner is optimized for guitar, it also works with other string instruments like bass guitars, ukuleles, banjos, and mandolins. Regardless of the instrument, the pitch detection technology will recognize the frequency.
