How to Tune Your Guitar Online? (Guide)
Welcome to the most accurate free online guitar tuner. This tool uses your device's microphone to detect the pitch of your guitar strings in real-time. It supports standard 6-string tuning (E-A-D-G-B-E).
Choose Your Mode:
- 🤖 AUTO Mode (Recommended for Beginners): Click the central "AUTO" button. Just play any string, and the tuner will automatically guess which string it is and tell you if it's sharp or flat.
- 🎸 Manual Mode: Select the specific string you want to tune (e.g., "6th E"). The tuner will only listen for that specific note.
Reading the Tuner:
Pluck a string and watch the needle:
- If the needle is to the Left (Red), the note is too low. Tighten the string slightly.
- If the needle is to the Right (Red), the note is too high. Loosen the string slightly.
- When the needle hits the Center and turns Green, your string is perfectly in tune! ✅
