the funeral march,
The cracked brass bells will ring;
To summon back the fire witch
To the court of the crimson king."
The black queen is Kali, the destructive aspect of the Goddess (Persephone in the Eleusinian Mysteries). The court of the crimson king is consciousness (the head). The black queen chants the funeral march (representing the death of the ego). The cracked brass bells (the divided psyche) will ring ... to summon back the fire witch" (Kundalini-Shakti) from dormancy at the base of the spine to consciousness in the head.
