Reference Tones (Standard Tuning)
Click a string to hear its reference pitch. Tune your guitar string to match.
Pro Tips
- Tune in a quiet environment for best accuracy
- Pluck the string firmly and let it ring out -- avoid muffled or buzzing sounds
- Always tune up to pitch, not down, to avoid string slippage
- The green zone means you are within 5 cents of perfect pitch
- Use reference tones if your microphone is unavailable
