Professional Guitar TunerTune Your Guitar with Precision
Use reference tones to tune by ear, or use your microphone with a live pitch meter. The goal is simple: clear feedback you can trust while you make small peg adjustments.
Live Pitch Meter
Play a string and watch the meter respond instantly. You’ll see whether you’re sharp or flat, and how close you are to the target note.
Reference Tones (Tune by Ear)
Prefer tuning by ear? Use the string buttons to play reference tones and match your guitar without relying on microphone detection.
Clear Visual Feedback
A simple needle and status text make it obvious what to do next: tighten if the pitch is low, loosen if it’s high, and aim for the center.

How to Use the Guitar Tuner
A practical workflow that works for most guitars and most rooms.
Allow Microphone Access
If you want live detection, click “Start Tuning” and allow microphone access. If you accidentally blocked it, reopen site permissions in your browser settings and try again.
Select Your String
Pick the string you’re tuning. Many players start from low E and move upward to keep tension changes predictable.
Pluck the String
Pluck once, let the note ring, and watch the meter settle. Avoid strumming multiple strings at once.
Fine-Tune Each String
Make small peg turns and re-pluck. If the meter looks unstable, mute the other strings, move closer to the mic, and avoid playing over background noise.

Frequently Asked Questions
Q1.How accurate is it?
Accuracy depends on your microphone and room noise. For best results, pluck one string at a time, get closer to the mic, and mute other strings.
Q2.Why is the pitch jumping around?
Overtones, echo, and background noise can cause the meter to move. Try a quieter room, pluck closer to the bridge, and dampen other strings.
Q3.It’s not detecting anything—what should I check?
1) Check site microphone permission. 2) Select the correct input device. 3) Close apps that may be using the mic (Zoom/Meet/Discord). On iPhone/iPad, also check iOS Settings → Safari → Microphone (and per-site settings) if detection still fails.
Q4.Can I tune by ear without using the microphone?
Yes. Use the string buttons to play reference tones and match them by ear.
Q5.What’s the best setup for mic tuning?
Use a quiet space, keep the mic close, and avoid strumming. One clean pluck per check is more reliable than constant picking. If possible, turn off steady noise sources (fans/AC) for a minute.
Q6.Should I tune up or down to pitch?
Tune up to pitch for stability. If you’re sharp, loosen below the target note, then tune up to it.
Q7.How often should I tune?
Most players tune each time they play. Temperature, string stretch, and playing style can all pull a guitar out of tune.
Q8.Does it work on mobile?
Yes, as long as your mobile browser supports microphone access. If mic prompts don’t appear, check browser site permissions and OS privacy settings.
Q9.My guitar won’t stay in tune—what then?
Old strings, slipping tuners, or a binding nut can cause tuning instability. Try new strings first; if the problem persists, consider a basic setup.
Q10.Can I play reference tones out loud while using mic mode?
Sometimes, but it can confuse detection because the microphone may pick up the speaker output. For best results, use headphones for reference tones or switch to tune-by-ear mode.
Q11.Can I use this for ear training?
Yes. Play a reference tone, then try to match it by ear. Start with one string at a time and short notes—accuracy improves faster than with long ringing chords.
Guitar Tuning Tips & Best Practices
Practical tips that help most players tune faster—especially on phones and in noisy rooms.
Pluck one string once and let it ring; don’t strum chords while the meter is listening. Mute the other strings to reduce sympathetic vibration. Tune up to pitch for stability: if you’re sharp, loosen below the target and then tune up. If the meter is unstable, move closer to the mic and reduce steady noise (fans/AC). If you’re using reference tones, avoid playing them on loud speakers while mic mode is on—use headphones or switch to tune-by-ear mode instead.
