在线吉他调音器

This browser-based tuner works with any guitar that produces sound your microphone can pick up. For acoustic guitars, hold your device near the sound hole for the clearest signal. For electric guitars, tune unplugged or with a clean tone at low volume. Distortion and effects add harmonics that can confuse pitch detection. The tuner reads the fundamental pitch the same way whether you play a steel-string acoustic, a nylon-string classical, or a solid-body electric.

Use the instrument navigator above to switch between Guitar 6-String, 7-String, 12-String, Bass, Ukulele, Violin, Mandolin, Banjo, Cello, Viola, Fiddle, Balalaika, and Cavaquinho. Each instrument loads its own set of tunings you can select from the tuning picker. For guitar, that means 27 presets including Standard EADGBE, Drop D for heavier riffs and power chords, Open G for slide and blues, DADGAD for fingerstyle and Celtic folk, and Half Step Down used by Jimi Hendrix and Stevie Ray Vaughan. Bass players get Drop D, Drop A, and 5-string setups. Ukulele covers Low G, Slack Key, and Soprano in D. Banjo includes Open G, Open D, Double C, and Sawmill, all accessible in two taps. Pick your instrument, pick your tuning, and start tuning right away in the browser with no app download required.
