A gentle ping follows a steady note within 5 cents. Its volume follows the sound slider. Microphone audio stays on your device.

Check your intonation.

Compare one open string with the same string pressed at fret 12. Remove your capo and mute the other strings.

  1. 1. Tune and measure the open string
  2. 2. Press at fret 12 and measure again

Press just behind fret 12 with normal pressure. Do not play a harmonic. Repeat the comparison to confirm the result.

Check your six strings.

Press start, then sweep gently across all six open strings, from thickest to thinnest. Let them ring together.

Remove the capo and tune the open strings to E2 A2 D3 G3 B3 E4. Fit the capo just behind fret 6, then enable “Check with capo on”. Listen to the reference tones or enable the microphone. Pluck each string without pressing another fret. Do not tune the open strings up to the capo targets.

What happens to familiar chord shapes?

Compare the halfway-octave relationship

Six semitones is half an octave in interval distance, but the frequencies are multiplied by the square root of two, not by one and a half. The calculated target table is more useful than estimating a midway frequency.

Sounding chord names at this fret

The root moves by 6 semitones; chord quality stays the same. A minor shape remains minor and a seventh shape remains a seventh. These examples describe transposition, not a song transcription.

DG♯ majorG♯ minor
EA♯ majorA♯ minor
GC♯ majorC♯ minor
AD♯ majorD♯ minor

The calculation behind the targets

Every open frequency is multiplied by 2^(6/12), approximately 1.41421. The standard low E at 82.41 Hz becomes 116.54 Hz; the high E becomes 466.16 Hz. These values assume equal temperament and A4 = 440 Hz. A different live calibration changes the frequencies while retaining the interval.
