What are the frequencies of standard guitar tuning?

Standard EADGBE at A4 = 440 Hz is E2 ≈ 82.41 Hz, A2 = 110.00 Hz, D3 ≈ 146.83 Hz, G3 = 196.00 Hz, B3 ≈ 246.94 Hz and E4 ≈ 329.63 Hz, from the lowest to the highest string.

How is drop D different from standard?

Drop D lowers only the 6th string from E2 to D2, leaving the other five strings unchanged. It makes power chords on the low strings playable with one finger.

Is this an audio tuner?

No — it is a reference table of target frequencies. Use it alongside a tuner or your ear. No microphone or network access is used.

Guitar tuning reference — notes and frequencies

A quick reference for the most common guitar tunings: standard (EADGBE), drop D, half-step down, DADGAD and open G. For each, you get the note name and exact frequency in hertz for every string, low to high.

Tuning frequencies use 12-tone equal temperament from an adjustable A4 reference, so you can match 440 Hz concert pitch or any alternative. Computed entirely in your browser.
