DESCRIPTION:
from Dune, by Frank Herbert
Semuta: A combination of a specific drug and music, which penetrated to the deepest levels of consciousness.

The drug is defined in the Appendix to Dune as "the second narcotic derivative (by crystal extraction) from the burned residue of elacca wood. The effect (described as timeless, sustained ecstasy) is elicited by certain atonal vibrations referred to as semuta music."

A quote from Dune: "The guard captain, Iakin Nefud, squatted on a divan across the chamber, the stupor of semuta dullness in his flat face, the eerie wailing of semuta music around him."
