Frequency Table** The basic formula for the frequencies of the notes of the equal tempered scale is given by fn = f0 \* (a)n where f0 = the frequency of one fixed note which must be defined. A common choice is setting the A above middle C (A4) at f0 = 440 Hz. n = the number of half steps away from the fixed note you are. If you are at a higher note, n is positive. If you are on a lower note, n is negative. fn = the frequency of the note n half steps away. a = (2)1/12 = the twelth root of 2 = the number which when multiplied by itself 12 times equals 2 = 1.059463094359... The wavelength of the sound for the notes is found from Wn = c/fn where W is the wavelength and c is the speed of sound. The speed of sound depends on temperature, but is approximately 345 m/s at "room temperature." --- [**http://www.sacred-geometry.es/?q=en/content/concert-pitch-a432-and-c128**](http://www.sacred-geometry.es/?q=en/content/concert-pitch-a432-and-c128) **On the concert pitch A=432 and C=128** Table 1 compares the frequencies of the individual tones using the three tuning methods, in the previous two scales as well as in the Just Intervals Scale. ![](4321.jpg) ![](A440vsA432.png) --- [**http://www.harmonymixer.com/blog/432-hz-music-a-higher-state-of-consciousness/**](http://www.harmonymixer.com/blog/432-hz-music-a-higher-state-of-consciousness/) **432 Hz Music a|A Higher State of Consciousness?** ![](cymatic432.jpg) ...So letas look at the A=432 Hz music scale There are a few ways to calculate this so weall look at the 2 most important scales a Pythagorean and Ptolemy tuning and compare them to the 440Hz scale. **440 Hz v 432 Hz** The first thing you may notice is that when A=432 all of the main notes are now whole numbers. Not only that, all of the main notes in the A=432 Hz scale are found in the most harmonics numbers chart. ![](harmonicnumbers.jpg) **How the table works** The column down starts at 1 and is then 2 x 2 x 2 x 2 etc The row across starts at 1 and is then 3 x 3 x 3 x 3 etc The numbers in the middle are the sums of the columns and rows multiplied e.g 432 is 16 x 27 In the first column we can see 256 highlighted. This is note C from the A=432Hz musical scale a|and so is every other number in this column. When you double the number to 512, 1024 etc, you are going up an octave each time. Likewise, halving the number to 128, 64 etc is going down an octave each time. In the 2nd column every note is G in the A=432Hz scale. Every number in the 3rd column is the note D, and so on. Every number in this table corresponds to a note in the A=432Hz scale. **Platonic solids** The 5 platonic solids are said to be the building blocks of matter. These figures and their different combinations, reveal every possible molecular structure and every possible geometrical law, forming our physical reality. When you add up all the angles within these 3D shapes you get: Tetrahedron 180 x 4 = 720 which is Note F# in the A432Hz musical scale (an octave above 360) Cube (360 x 6) 2160\* (Note A) Octahedron 1440\* (Note D) Dodecahedron 6480\* (Note E) Icosahedron 3600\* (Note F#) \* You may think that 1440 can not be musically harmonious with 144 (note D), but it is. If you multiply a frequency by 10 you will get itas 10th harmonic overtone which is 3 octaves + a major third, so adding or removing 0as is no problem at all from a musical and harmonic point of view.

They did this by directly measuring the infrared absorption spectra of DNA molecules. These DNA frequencies were then arranged as ascalesa of tones, and subsequently used as the basis for Alexjanderas musical compositions... ..Then, after weeks and weeks of experimentation with different sound combinations, a atonal centera began to emerge. One pitch in particular seemed to lend meaning and coherency to the challenging microtonal morass a a pitch common to all four bases: C#(!)
