How to Tune Your Guitar by Ear or with a Mic
Tuning your guitar is the most important skill you can learn as a beginner. An out-of-tune guitar will make even the greatest players sound bad. Our online guitar tuner simplifies this process. Simply allow microphone access, pluck a string, and our advanced pitch detection algorithm will tell you exactly which note you are playing and whether it is too sharp (high) or flat (low).
The standard tuning for a 6-string guitar, starting from the thickest string (lowest pitch) to the thinnest string (highest pitch), is E - A - D - G - B - E. A helpful mnemonic device to remember these notes is: "Eddie Ate Dynamite, Good Bye Eddie".
Exploring Alternative Tunings
While standard tuning is extremely versatile, exploring alternative tunings can unlock entirely new sonic possibilities and make certain chords easier to play. Our tuner supports dozens of alternative tunings instantly.
- Drop D (D A D G B E): Popular in rock and metal for easy, heavy power chords. Lower the thick E string down a whole step to D.
- Open G (D G D G B D): A favorite of blues players and the Rolling Stones. Strumming all strings open produces a G major chord.
- Half-Step Down (Eb Ab Db Gb Bb Eb): Lowers the tension on the strings, making bending easier, and creates a darker, heavier tone.
Frequently Asked Questions
Is the online guitar tuner accurate?
Yes, GuitarTunePro uses the Web Audio API and highly precise algorithmic pitch detection. It is accurate to within ±1 cent, making it suitable for professional stage setup, recording sessions, and daily practice.
Why isn't the tuner hearing my guitar?
Ensure that you have granted microphone permissions in your browser. If you are using an electric guitar without an amplifier, the acoustic sound may be too quiet. Try moving your instrument closer to the device's microphone or plugging into a USB interface.
