No, I don't actually refer to this as "Double Power Chord", in my mind it's the "Alice In Chains Chord", for reasons explained in the video below.
Today I'd like to introduce you to my favourite chord of all time. Behold:
In my mind this chord could actually be any one of 3, depending on which note you decide to be the root:
- - If the deepest pitch is the root then the middle note is it’s 5th, and the higher note is a 2. That makes the chord a Sus2.
- - If the middle note is the root, that makes the deeper note a 4th; while the higher note is a 5th. So this chord is an Inverted Sus4.
- - If the highest note is the root, then the middle pitch is a 4th, while the lowest pitch is a m7…. Root, 4th, m7th…. I don’t think there’s a name for that chord to be honest…
EDIT: Having spoken with a musical colleague we came to the conclusion that, you could refer to this chord as Inverted Stacked Fourths. Maybe read-up on Quartal Harmony for more info.
