About Hells Bells
The opening track of Back in Black (1980), the first album after Bon Scott's death, starting with a tolling bell. It is in A minor in plain E Standard: the guitar intro picks through open-string chords before the band comes in.
Measured from a compilation copy (an unofficial Russian Greatest Hits CD) that runs as long as the official track, the song sits about 6 ¢ sharp (A ≈ 441.4), as good as concert pitch. Fans call Back in Black the first AC/DC album at A 440, and the four songs TuneLit measured from it all land within 7 ¢. Tune sets E Standard 6 ¢ up; at plain A 440 most ears will not hear the difference.
The bell is a poor tuning reference: its overtones do not line up the way a string's do, so it can make a well-tuned guitar seem off. Judge your tuning against the guitar intro instead.
Tip: Tune before you press play, then check against the picked guitar intro that follows the bell, not against the bell itself.
Step by step
Tune your guitar like the record
- Tap Tune like this: the tuner switches to E Standard, every string +6 ¢, the notes Hells Bells was recorded in.
- Turn String 6 to String 1 until each shows ✓ in tune. Hells Bells sits 6 cents sharp on the record: at A 440 your guitar would sound that much flat against it, which Tune already corrects.
- Then play Hells Bells along with the record: its lowest open note and your String 6 should ring together without a wobble.
Or the other way round
