YOUR SONG SETUP
Before you play Seven Nation Army.
This setup follows the open-A rhythm guitar part. The familiar low riff also uses an octave effect; lowering your strings an octave is not a substitute for that effect. The linked arrangement includes other guitar parts with different targets.
Tune with the capo removed. Follow the capo position in the specific arrangement you are learning; different guitar parts can use different positions.
Choose the guitar part you are learning.
Studio, live or acoustic version?
A different recording, guitar part or lesson may use a different setup. Open that arrangement and check its tuning and capo instructions. Use custom string targets if it differs, then save it in My guitars.

Why isn’t the microphone picking up my guitar?
Allow microphone access in your browser, move closer and reduce background noise. Pluck one open string at a time and let it ring. If access is blocked, check your browser’s site settings or use the reference tones instead. Microphone tuning requires a secure HTTPS connection.
Is my audio recorded or sent anywhere?
No. The tuner analyses microphone audio locally in your browser. It does not record, save or upload your playing. Press “Stop listening” to release the microphone.
