To match the key in the song, tune down a full step to D standard. Sounds great in E though!
Verse 1 (hummed, not sung)
Am C D Am
Bm D Am
Bm C D Em
C Bm Am
Verse 2
Am C D Am
Far over the misty mountains cold
Bm D Am
To dungeons deep, and caverns old
Bm C D Em
We must away, 'ere break of day
C Bm Am
To find our long forgotten gold
Verse 3 (slight change)
Am C D Am
The pines were roaring on the height
Bm D Bm
The winds were moaning in the night
Bm C D Em
The fire was red, it flaming spread
C Bm Am
The trees like torches blazed with light
END. I like to hum another verse and gradually slow down
