I came across with this video
The chords are E - G♯ - C♯m - B
My question is: why is G♯ a major chord in this progression? I thought that since the root of the scale is E (major) the third chord (which is G♯) should be minor, unless the scale of this progression is not E major. Am I right?
Thank you! I would like you to explain me this. I'm just trying to understand how certain chords are used while playing a certain scale.
