How to tune to Standard
- 1Tap Start Tuning. Allow microphone access when your browser asks. Nothing is recorded or uploaded, everything runs on your device.
- 2Pluck one string at a time. The tuner detects the pitch and tells you which string you're closest to: E, A, D, G, B, or high E.
- 3Watch the needle. Left of center means flat, tune up. Right of center means sharp, tune down.
- 4Confirm the lock. When the needle centers and turns green, the string is in tune. Move to the next string and repeat.
What is Standard tuning
Standard guitar tuning, E A D G B E from the lowest string to the highest, is the tuning nearly every guitar method, songbook, and beginner lesson assumes you're using. It has been the default for acoustic and electric guitar for well over a century, and the overwhelming majority of recorded music, from folk and country to pop, rock, and jazz, is written and played in standard tuning.
Part of the reason it stuck is balance. The intervals between strings, mostly perfect fourths with one major third between the G and B strings, put common open chord shapes like E, A, D, G, and C within easy reach. That same layout is what makes chord theory taught from standard tuning transfer cleanly to other instruments tuned in fourths, like bass or mandolin family instruments.
Nearly any song you can name, from Eric Clapton's blues playing to modern pop and country radio, was tracked in standard tuning unless the artist specifically mentions an alternate. If you're learning guitar for the first time, or picking up a song from a book or a tab site without a tuning note attached, standard EADGBE is almost always the right starting point.
Frequently asked
How accurate is the Savior Guitar online tuner?
The tuner uses the YIN pitch-detection algorithm with parabolic interpolation, the same family of algorithms used in many professional tuners. Accuracy depends mostly on your environment. A quiet room and a single plucked string will give you readings within a couple of cents.
Why does the low E string read unstable?
Low frequencies are harder to detect reliably because the wavelengths are longer. Pluck the string firmly, let the initial pick attack fade, then watch the needle. If it still wobbles, mute the other strings with your palm.
Does this work on phones?
Yes. It runs in any modern browser, including Safari and Chrome on iOS and Android. You'll be asked to grant microphone access once.
Do you store my audio?
No. All pitch detection happens in your browser. Nothing is uploaded, recorded, or stored. The microphone stream lives only in your device's memory while you're using the tuner.
What's standard guitar tuning?
From low to high: E2, A2, D3, G3, B3, E4. The tuner auto-detects which string you're playing and shows you how far sharp or flat you are.
