About Castle of Glass
Castle of Glass, a mid-tempo single from Living Things (2012), is in plain E Standard (E A D G B E). Songsterr writes all of its guitar layers in standard tuning, with no dropped string and no capo, which makes it one of the easiest Linkin Park songs to tune for.
At about 2 cents flat, Castle of Glass is as close to A 440 as a record gets, so any standard tuner will do, and TuneLit's check from the audio hears the open low E (0.971). The record's low end centres on C♯ and B rather than on E.
The surprise is its neighbours: Lost in the Echo, In My Remains and Burn It Down all drop the 6th string to D, so if you play Living Things in order, bring the 6th string back up to E before this one, or the lowest notes will sit a whole step too low. Linkinpedia lists live versions in a different key, two and a half steps higher, so concert videos may not match the album. With all six strings at standard pitch, this is also a good song to check that your guitar's intonation holds up the neck, since nothing is slackened.
Tip: Plain E Standard at A 440; if you come from Burn It Down, bring the 6th string back up from D to E first.
Step by step
Tune your guitar like the record
- Tap Tune like this: the tuner switches to E Standard, the notes Castle of Glass was recorded in.
- Turn String 6 to String 1 until each shows ✓ in tune. Castle of Glass sits at concert pitch on the record, so the tuner stays at A 440.
- Then play Castle of Glass along with the record: its lowest open note and your String 6 should ring together without a wobble.
