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.

Experimental: overlapping notes can be unclear. Select any result to measure that string alone in this window.

Check a known reference.

Play a steady reference from another device or instrument whose frequency you know. Enter that frequency below.

This compares your input with the reference you supply. It is not a certified calibration. Only numbers are saved, never audio.

By ear: click a note, match your string, then move to the next. Keyboard: 1–6 to play · Esc to stop

KNOW YOUR TUNING

Drop C♯: C♯ G♯ C♯ F♯ A♯ D♯

From standard, lower the thickest string by three semitones and every other string by one semitone. If you are already half a step down, lower only string 6 another whole step.

The table shows the open-string setup at A4 = 440 Hz. For capo pitches, use the capo controls above.

THE TUNEGUITAR GUIDE

A setup plan for Heart-Shaped Box

TuneGuitar guide · Updated 6 October 2026 · How we prepare our guides

What to check for this arrangement

This main-guitar setup is Drop C sharp, with an overdub entry using the same notes. Coming from Come As You Are, the change is not a uniform half-step shift: the fifth through first strings rise one semitone, while the sixth falls one. The transition table makes that mixed direction explicit.

Which guitar part does this page cover?

The selected part is Main Guitar in the linked Nirvana arrangement. The table exposes the part alternatives retained in our source record; repeated targets can still belong to different musical lines. It is not a complete inventory of every performance or recording.

complete Drop C♯.

Plan the next song without guessing

This comparison calculates changes from this selected source part to the other stored arrangements. It compares open notes only. Check any capo, A4 reference and instrument change separately; unchanged targets still deserve a quick drift check.

If your lesson disagrees

Check the named part and recording version before choosing between the sources. A missing capo value means it has not been verified here, not that a capo is forbidden. Use Custom strings for a genuinely different target sequence, or prepare a correction with a source link. Do not retune solely because a processed guitar sound seems lower.
