I am very new to all this, and I am so glad I found this forum! Anyway, today I attempted to learn Adele's Remedy (Available on Spotify now) by ear, and when I checked my work against an existing tab I ran into a couple issues.
Intro: G D A
Chorus: D A G Bm
Key: D major
Intro: Em D A
Chorus: D A Em G Bm
Key: (they say Eminor, but I think it should still be Dmajor)
After listening to the song again, I am pretty sure I was wrong and their chords are right, but in either situation I think that the song is in the key of D major, since no A major chords would usually exist in Em? Also I feel like i can hear the song resolve to D. My final concern is that playing a G instead of Em sounds ok, but it is obvious that Em is the correct choice. Any Idea why this is/how can I avoid making the same mistake in the future?
