Side 1: A Lambdoma matrix was played as the background music for Barbara's talk with a fundamental frequency of 355 cycles per second which was her translation of the diameter of the earth into a musical interval raised to an audible octave. Barbara's talk deals with the material which became the article "International Harmony Based on a Music of the Planetary Grid System." Barbara Hero's lecture was recorded at a workshop given at the 1985 Coptic Convention in Albion, Michigan.
Side 2: Joseph Jochmans speaks of the energy patterns of the earth, and relates them to evolving geometric solids which eventually become the future grid system of our planet. He mentions how different angles have different frequencies, and asks "What is the new song of New Jerusalem, what is the new harmonic?"
