FreeNote CD Track Talk for 13 O’Clock Blues Band’s Devils’ Dance
Leading off with the title track, Devil’s Dance begins with Babe’s solo piano intro, and then the band enters and slams into the main chord riff, C7 to C half flat 7. These two Harmonic 7th chords are just a Septimal 7th apart. This CD is based on a C of 528 Hertz, and in the ancient Solfeggio system, the pitch 741 Hertz is opposed to C, and in disharmony with it, earning it the name ‘Devil’s Tone’. The guitar solo features a Harmonic Cloud which adds the 11th Harmonic, which is close to the Devil’s Tone but is actually a consonance. In this way, the power and dissonance of that 741 Hertz tone has been reduced and replaced with the 11th Harmonic, a new consonance. The addition of the 147th Harmonic in the Cloud further reduces 741 by reversing it.
