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.

THE TUNEGUITAR GUIDE

A setup plan for Wake Me Up When September Ends

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

What to check for this arrangement

The selected acoustic source uses standard, giving the same open targets as American Idiot and Holiday in this catalogue. Keep separate guitar profiles if you switch instruments during the session. Their intended notes can match while their microphone level, fretting response and physical drift differ.

Which guitar part does this page cover?

The selected part is Acoustic Guitar in the linked Green Day 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.

The table starts from E2 A2 D3 G3 B3 E4 at A4 = 440 Hz. If your guitar is already in another tuning, use its actual starting notes rather than repeating these adjustments. For the musical structure and physical considerations of this setup, read the

complete Standard.

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.
