Further details are given later in this article. Another key point is to play them on a non-electrical instrument: Maria Renold observed that otherwise the inherent qualities of a tone are lost. Independently of this author, several musicians and teachers have made similar observations. Many comparisons with the same results were made using different instruments, so the individual quality of the tones originates in the tones themselves and not in the instruments on which they are played. Over 90% of people found that the tones from the A=440Hz tuning method sounded uncomfortable, irritating and unpleasant, whereas the tones obtained from the A=432Hz tuning method sounded peaceful, pleasant and full. The results were astonishing: almost all of the people found unmistakably and individually different qualities between tones representing the same musical note in the two tuning methods. This way she eliminated the influence of the interval structure of any scale.

To rule out the possibility that this behavior was only found in her particular scale, she conducted a series of aural experiments on more than 2000 people on several countries comparing a pair of individual tones obtained from both tuning methods (A=440Hz and A=432Hz). These findings show that tones of certain frequencies hide characteristic qualities which can have major effects on human beings. The comparison was made over many years and in many places, and the same phenomena always took place.
On the other hand, intervals and tones have a beautiful, pleasant and harmonic effect on the human being when tuned to A=432Hz. She reiteratively observed that the intervals and tones become antisocial, and indeed cause people to provoke one another when the concert pitch A=440Hz is used. In last section, we explained the practical findings of musician researcher Maria Renold when playing music in her new scale of twelve fifths. Modern instruments are tuned by fixing not the tonic, but the sixth note in the scale to a frequency or concert pitch A=440Hz. Once the frequency of a note is fixed, the frequencies of the remaining notes in the scale become also fixed, according to the relative intervals given by the structure of the scale. The frequency of every note is usually given in a normalized way: it is referenced to the frequency of the first note, called the tonic. Scales define the intervals between frequencies of all the notes in an octave. Scales were compared, and we reported some aural or qualitative differences in the sound of similar intervals from different scales. In the first part of this article the structure of modern and ancient musical scales was described in detail. 2.- Comparing the scales in concert pitch A=440 and A=432ģ.- Experiments with individual tone frequenciesĤ.- Tuning frequencies for the Greek Aulos Modes
