Welcome to the most accurate, zero-latency online guitar tuner. Whether you play an acoustic, electric, or bass guitar, our chromatic tuner uses your device's built-in microphone to provide real-time, professional-grade pitch detection. No app installation or downloads are required; simply grant microphone access and start tuning.
Highly accurate chromatic pitch detector
Click the "Start Tuning" button and pluck a string. The tuner will automatically detect the pitch and display the closest musical note. The visual meter indicates whether your string is flat (too low), sharp (too high), or perfectly in tune. Standard E-A-D-G-B-E string indicators will highlight to help beginners map standard guitar strings to the correct pitch.
Unlike standard tuners that only recognize six specific strings, a chromatic tuner detects every note in the musical scale. This allows for alternate tunings (like Drop D or Open G), tuning with a capo, or tuning entirely different instruments like ukuleles, violins, and mandolins.
