Septimal minor third

http://en.wikipedia.org/wiki/Septimal_minor_third

In music, the septimal minor third play (help·info), also called the subminor third (by eg Helmholtz^[2][3]) is the musical interval exactly or approximately equal to a 7/6 ratio of frequencies^[4]. In terms of cents, it is 267 cents, a quartertone of size 36/35 flatter than a just minor third of 6/5. In 24-tone equal temperament five quarter tones approximate the septimal minor third at 250 cents ( Play (help·info)).

The septimal minor third may be derived from the harmonic series, as the interval between the seventh and sixth harmonics, and as such is in inharmonic ratios with all notes in the regular 12TET scale.^[5] It has a darker but generally pleasing character when compared to the 6/5 third. A triad formed by using it in place of the minor third is called a septimal minor or subminor triad play (help·info); however in fact that chord is a part of the overtone series, or in other words is an otonal chord, with ratios of 6:7:9, whereas the ordinary minor third is a utonal chord. While the septimal minor third is classed as a 7-limit interval, and the septimal minor triad as a 9-limit chord, the fact that the chord is otonal makes it sound perhaps about as consonant as the just minor triad.

There is a special sound and color of love according to Dr. Horowitz, a Harvard-trained award-winning investigator. Broadcasting the right frequency can help open your heart, prompt peace, and hasten healing. “We now know the love signal, 528 Hertz, is among the six core creative frequencies of the universe because math doesn’t lie, the geometry of physical reality universally reflects this music; these findings have been independently derived, peer reviewed, and empirically validated,” Dr. Horowitz says.

The third note, frequency 528, relates to the note MI on the scale and derives from the phrase “MI-ra gestorum” in Latin meaning “miracle.” Stunningly, this is the exact frequency used by genetic biochemists to repair broken DNA – the genetic blueprint upon which life is based! MI – 528 Hz – relates to crown chakra. Dr Puleo suggests an association with DNA integrity.

The regular “C” that we all know of in this culture (which is from the diatonic scale of do, re, mi, fa, so, la, ti, do) is not the 528 Hz frequency “C.

A regular “C” vibrates at a frequency of 523.3 Hz.

The “C” of 528 Hz used for DNA repair is part of an ancient scale called the Solfeggio Scale.
