Free Online Guitar Tuner
Get your guitar in tune in under a minute, right in your browser. This tuner listens through your phone or laptop microphone and shows you which way to turn each peg — made for worship leaders and church musicians who need to be ready before the first song.
Microphone audio is processed in your browser — never recorded or sent to us.
How to tune your guitar
Allow the microphone
Tap the tuner and choose “Allow” when your browser asks for the microphone. Sit close to your phone or laptop, away from fans, chatter and other instruments, so it hears only your guitar.
Pluck one string at a time
Start with the thickest string, low E. Let it ring and watch the display: if the note reads flat, tighten the peg a little; if it reads sharp, loosen it. Small, slow turns settle on the centre faster than big ones.
Go across, then check again
Work through A, D, G, B and high E. Tightening one string slightly changes the pull on the others, especially with new strings, so run across all six once more before you start playing.
Common guitar tunings
Almost every hymn chart, including the chords on Praise & Worship, assumes standard tuning. The others are worth knowing for particular songs, singers and moods. Notes are listed from the thickest string to the thinnest.
| Tuning | Notes (low to high) | When it helps in worship |
|---|---|---|
| Standard | E A D G B E | The default for nearly all chord charts, hymnals and band arrangements. |
| Drop D | D A D G B E | A deeper, fuller bass note for songs in D, and easy one-finger power chords. |
| Half-step down | E♭ A♭ D♭ G♭ B♭ E♭ | Lowers every song by a semitone to suit a singer or match a recording. |
| Open G | D G D G B D | Strumming the open strings gives a G chord; good for slide and simple accompaniment. |
| Open D | D A D F♯ A D | A ringing, drone-like sound for quiet reflective songs in D. |
| DADGAD | D A D G A D | An open, Celtic-flavoured tone that suits meditative hymns and fingerpicking. |
Tuning with the rest of the band
If you play with a keyboard or piano, everyone should agree on the same reference pitch. Most digital keyboards and this tuner use A = 440 Hz, so tuning to the tuner first and then checking one chord against the keyboard keeps everyone together. An acoustic piano that has not been serviced in a while may sit slightly flat; in that case tune your guitar to the piano rather than the other way round.
If you use a capo, tune without it first, then clip it on and check again — a capo can pull the strings a little sharp.
Frequently asked questions
Is this guitar tuner really free?
Yes. The tuner is free to use as often as you like, with no account, no subscription and no app to install. It is provided by GuitarApp as a free widget and embedded here so that church musicians using Praise & Worship can tune up in the same place they find their hymns and chords.
Does the tuner record my audio?
No. The tuner needs the microphone only to hear the pitch of the string you are playing. That listening happens inside your browser while the page is open; nothing is recorded or sent to Praise & Worship. You can withdraw microphone permission at any time from your browser’s site settings, and the tuner simply stops listening.
Why can’t the tuner hear my guitar?
Usually the browser has blocked the microphone. Look for a lock or settings icon beside the web address, allow the microphone for this site and reload the page. Also make sure no other app, such as a video call, is using the microphone, and hold your phone close to the guitar in a quiet room.
How often should I tune my guitar?
Tune every time you pick the guitar up, and check again just before the service begins. Strings drift with changes in temperature and humidity, and a warm, crowded church can pull a guitar out of tune between rehearsal and the first hymn. New strings stretch for a few days, so expect to retune more often after restringing.
Should our worship band tune to A440?
For most teams, yes. A440 is the standard reference pitch used by digital keyboards, backing tracks and most tuners, so it keeps everyone together without fuss. The exception is an older acoustic piano that sits slightly flat or sharp. Since a piano cannot be retuned before Sunday, tune the guitars and other instruments to match it instead.
