In reference to Iasos’ ideas of a ‘Law of Octaves’ are based of Anthroposophist thought. In the chapter “The Esoteric World of Sound and Research into Harmonics”… Hamel talks about ‘The World Monochord’ a single string instrument created by the Pythagoreans to measure harmonics.
“The interval between sun and earth produces a ‘diapason materialis’, the Greek designmation for the octave, corresponding on the left to a proportio dupla, i.e 1:2. Further ‘material’ intervals protrayed include diatesseron (i.e, the fourth), diapente (the fifth), diapason cum diapente etc. The whole universe is thus divided into a double octave, with the sun at its centre… Examination of the interval system reveals the absence of the tierce or third. The octave and fifth rule the universe as the basis of all our music; and indeed it was only later that the chord of the third entered man’s conceptual horizons as a typically ‘human’ phenomenon.” Manel quotes F. Stege: Musik, Mystik, Remagen 1961, p. 133.
“It is precisely this experience of the single note that the significance of the intervals that are once more of interest in the new spiritual music. Rulolf Steiner was already interpreting the intervals in his day, associating subjectivity and destiny with the ‘experience of the third’, the discovery of the higher self with ‘octave experience’ and imagination with the ‘fith experience’.
These are interesting quotes related to Iasos ‘law of octaves’, which nicely links back into esoteric thought, this law of octaves, linking nicely with Steiner’s work and the mention of Thoughtforms. I will try to also find a quote relating to ‘Saint Germain’, as I believe that’s another useful link. Iasos is one of the pioneers of New Age, so it is quite lucky that I can find a link between Theosophy and New Age through him. However, he does technically refer to himself as a creator of heavenly, celestial inter-dimensional music. I don’t have time to unpack anymore of Iasos ideas in this essay, but these nicely link to Thoughtforms.
