Concept
When starting to work on what would become
Octavarium, Portnoy noted that it would be their eighth studio album and that they had recently released their fifth live album,
Live at Budokan. This sequence mirrored the
octave on a
musical keyboard: each octave contains eight
naturals and five
accidentals. Portnoy suggested that they use that concept for the entire album.
[11] When writing, the band delegated each song a different
key. Sound effects were placed between songs to connect them: for example, "
The Root of All Evil", written in
F minor, and the following track, "The Answer Lies Within", written in
G minor, were connected by a sound effect in the key of
F♯ minor. The album's lyrics and song titles featured references to this concept. Portnoy cited the titles "The Root of all Evil" (referring to the musical term "
root") and "Octavarium" ("the octave of the octave") as two examples of this.
