4. Transcendental Constant Music Scale Tables part 3
An attempt at getting the exact value of the key A4 = 440.00 Hz (in piano frequency).
While playing with the numbers I noticed that Ln ( frequency D0/ Fundamental frequency fF) = - ( constant C16/ constant C8 i.e. pi ).
The equation looks like this:
Ln ( 18.2235960 Hz / ffundamental ) = - ( 9.99983879780488 / 3.14159265358979312)
It simplifies as follows:
Ln ( 18.2235960 Hz / ffundamental ) = -3.18304755
e-3.18304755 = ( 18.2235960 Hz / ffundamental ) = 0.0414591137
Giving finally the fundamental value of the frequency ffundamental:
ffundamental= 439.555851 [Hz]
Having fundamental frequency we can easily determine base of power in general formula for key notes:
( D0 = 18.2235960 Hz ) = [ X (-6-49)/12] * [ffundamental= 439.555851 [Hz] ]
This simplifies to:
X(-55 / 12 )= 0.0414591137
(-55 / 12 ) Ln X = Ln 0.0414591137
Ln X = 0.694483102
X = e0.694483102 = 2.00267363
and final equation for calculating the Transcendental Constant Notes is:
f ( n ) = [ ( 2.00267363 )( n - 49 ) / 12 ] * 439.555851 [Hz] [ Eqn. 1 ]
This fundamental frequency, fFundamental = 439.555851 [Hz] calculated from the constants, not by assigning some arbitrary number ( A4 = 440.00 Hz) looks much more interesting. It is time for experiments to check all these notes if they sound harmonious. I am pretty sure they do.
The minimum absolute difference in [Hz] equals to -0.12 at D0
The maximum difference is 36.09 [Hz] at B8
The relative difference varies from 0.002 to 0.0074
The tables contain five columns: 1st column- key number and the name of the key; 2nd column - Transcendental Scale Note frequency in Hz; 3rd column - Piano Scale Note frequencies in Hz; 4th column - Absolute difference between those frequencies in Hz, 5th column - The relative difference between these frequencies from column 4 ( absolute value divided over the frequency from second column - so it is similar to relative error)
