THE HOBBIT Soundtrack
Thorin Oakenshield versus Azog the Defiler
THE HOBBIT. AN UNEXPECTED JOURNEY
by Howard Shore

"The music of Azog has caused something of a stir this weekend.
Why does his last scene in the film include music we've previously
associated with Mordor? I can't fully answer that question,
but I can lead you a bit: Azog's primary theme is a descending pair
of thirds (G-Eb-F-D) with a chromatic snap at the end (Eb-D-Db).
Musically, Azog has a connection to Mordor's musical world from his
first appearance on. His final scene is very much in line with this
approach.
Why this consistent connection? We shall see ..."

"Azog was sent to Moria by Sauron, perhaps that's the connection."

" I was also thinking that maybe Azog did die of his wounds, but was resurrected by the Necromancer/Sauron?"

Chorus in Adûnaic:

Nêbâbîtham Magânanê
Nêtabdam dâurad
Nêpâm nêd abârat-aglar
îdô Nidir nênâkham
Bârî 'n Katharâd
