In all of Indian classical music, a form of solfege is the first lesson. In Indian classical music the corresponding sounds of solfege are Sa, Re, Ga, Ma, Pa, Dha, Ni and back to Sa. Keeping in mind that the vedas( Holy texts of Hinduism) were the source for this technique, this dates back to 1000-1500 BC. This is the earliest known origin of the solfege.
An alternative theory on the origins of solfège proposes that it may have also had Arabic musical origins. It has been argued that the solfège syllables (do, re, mi, fa, sol, la, ti) may have been derived from the syllables of the Arabic solmization system درر مفصّلات Durar Mufaṣṣalāt ("Separated Pearls") (dāl, rā', mīm, fā', ṣād, lām, tā') during the Islamic contributions to Medieval Europe. It is speculated that the reference to pearls might originate from the similar appearance of notes on a single line (the earliest known graphical musical notation) to a string of pearls. If so it can be taken as evidence that the Arabs had used or even invented a now lost staff notation system.
This origin theory was first proposed by François de Mesgnien Meninski in his Thesaurus
Linguarum Orientalum (1680) and then by J. B. de Laborde in his Essai sur la
Musique Ancienne et Moderne (1780).[6][7]
Guillaume Villoteau (Description
historique, technique et litteraire des instruments de musique des
orientaux in the Description
de
l'Égypte[1], Paris 1809) appears to endorse this view.(wikipedia)
As for the numbers involved lets look at
the nature of 432:
" Multiplications
of 8 cycles gives one the significant 432 (54 x 8, and 3 x 72). The
number 432 is considered sacred in a majority of the major temple
complexes of this planet. For instance, one side of the Great Pyramid,
Egypt, at its sea level foundation, is 432 Earth Units (51.49 cm).
The major Toltec complex of Teotihuacan in Mexico, has its great
Pyramid of the Sun with an overall base of 864 STU (Standard
Teotihuacan Units) which is twice 432. STU was the Toltecs measure unit
for this site, as their "myths" relay it was taught them by the Shaman
Wizard gods from the stars. Each side of this Sun Pyramid is 216 STU,
precisely half of 432, and 3 x 72."
