I Burn

"I Burn" is Yang Xiao Long's music theme. Three different versions of the song exist: the one featured in the "Yellow" Trailer, a hard rock version featuring a rap verse, and a club/dance remix of the hard rock version minus the rap verse.

It is also used as the ending song for the episode "Welcome to Beacon" of RWBY.

Composition
The single version features remixed versions of previous trailer songs, "Red Like Roses", "Mirror Mirror", and "From Shadows", as well as a shorter version of the "I Burn" album version.

The remixes of the previous trailer songs, as well as the I Burn song remix, are primarily influenced by electronic dance music, with synthesized instruments, heavily auto-tuned vocals and four-to-the-bar bass drums.

The album version of the song drops most of the electronic influence in favor of a hard rock sound. The song starts off with heavily distorted guitar chords which accompany the first verse. After the first verse and chorus, sung by Casey Lee Williams, a rough, atonal guitar solo with heavy use of artificial harmonics is played.

After the second verse and chorus, the bridge leads into two rap verses performed by Lamar Hall. His raps are far more rebellious in content, with a few instances of mature language, such as "Human Torch can't fuck with me" and "Shit will never be the same."

After the rap verses, Jeff Williams plays a cleaner, more melodic guitar solo before Casey takes back over, singing the song's chorus twice before the song ends.

The chorus, the first solo, and the bridge after the second chorus are in the key of C# minor, whereas the verses and the second solo are in the key of E minor.

Trivia
