Consider the 'retuning' in Rev. 5:12 (before Ascension) and Rev. 7:12--it's by 'circle of fifths'. (JBJ)
And someone could find the Tune of the Twelve (minor prophets) by having the death dates of each of the 12 put on an octave (use black keys too), and then seeing how they are transferred/retuned into the theological order of the twelve minor prophets.
And there's more retuning to be done, by psalmodic response: http://chuckhartmanhistoryconductor.blogspot.com/2011/11/astrology-or-naming-days-aright.html Let's get in tune!
