About Run to the Hills
Run to the Hills was the lead single from The Number of the Beast (1982) and a UK top-ten hit, a gallop that the drums and Steve Harris's bass drive from the opening bars. The record is in E Standard, but the guitars barely touch the open low E: in Songsterr's transcription Adrian Smith's rhythm part is mostly power chords on D, A, G and C, rooted at the 5th and 3rd frets of String 5 and the 5th and 7th frets of String 4, and palm-muted more than half the time.
TuneLit measured the album at about 2 ¢ sharp on the 1995 reissue, concert pitch, and Run to the Hills reads about 5 ¢ high; the 2015 remaster reads it about 3 ¢. Either way a guitar at A 440 sits with the record, and Tune sets plain E Standard.
If you know the song from concerts, you may have heard it differently: Adrian Smith says he now plays Run to the Hills in Drop D on stage, a habit he picked up after rejoining the band in 1999. That is the live version only. The 1982 recording is in E Standard, as every tab says and as TuneLit's check from the audio confirms. Dave Murray's lead part in the tab has about a hundred bends, so keep an eye on String 2 and String 3.
Tip: Stay in E Standard at A 440 for the record, and check the D at the 5th fret of String 5, where the verse riff keeps landing.
Step by step
Tune your guitar like the record
- Tap Tune like this: the tuner switches to E Standard, the notes Run to the Hills was recorded in.
- Turn String 6 to String 1 until each shows ✓ in tune. Run to the Hills sits at concert pitch on the record, so the tuner stays at A 440.
- Then play Run to the Hills along with the record: its lowest open note and your String 6 should ring together without a wobble.
