What key is Raining Blood in?

Published in Music Theory 2 mins read

The iconic Slayer song "Raining Blood" is primarily in the D♯ Phrygian key.

Understanding D♯ Phrygian

The Phrygian mode is a unique musical scale known for its dark and often intense sound, making it a fitting choice for a thrash metal anthem like "Raining Blood." It's one of the seven musical modes derived from the major scale.

Characteristics of the Phrygian Mode

  • Distinctive Interval: What gives the Phrygian mode its characteristic sound is its lowered second degree (a minor second or half step above the root). In D♯ Phrygian, this means the second note of the scale is a half-step lower than it would be in a standard D♯ minor scale.
  • Comparison to Minor: While similar to a natural minor scale, the crucial difference lies in that flattened second note. For D♯ Phrygian, the notes are D♯ – E – F♯ – G♯ – A♯ – B – C♯ – D♯. Notice the 'E' (E natural) which is a half step lower than E♯, the second note in a D♯ natural minor scale (D♯ E♯ F♯ G♯ A♯ B C♯ D♯). This small alteration creates a distinctive, often dissonant or exotic flavor.
  • Popularity: Within the realm of Phrygian keys, D♯ Phrygian is quite popular, ranking as the 7th most commonly used. Among all musical keys, it holds the 57th position in popularity. Its use in "Raining Blood" contributes significantly to the song's sinister and heavy atmosphere.
