From a musical standpoint, these frequencies are utter balderdash, and there is nothing ancient about them. They stem from NUMBERS that were given significance in medieval numerology, but just taking a number and deciding that it should mean cycles per second is just plain silly.
This scale sounds random and silly. About as meditational as your five year old daughter practicing on the violin for the first time in her life.
The Perfect Fourth occurs (with integer-ratio precision) twice, a very strong argument for the 'cycles-per-second' interpretation of the numbers. If some octave transposition is applied along with some pleasant sound-shaping, the tones are very meditative. I've been getting very encouraging responses from audiences. If a "major chord" sound is desired, it can be found be sounding the tones Re, Mi and La simultaneously.
