That is why, my boy, this 'Chinese seven-toned subdivision of the octave of sound,' simplified by Chai-Yoo, which has reached your contemporary favorites and is now used for all the sound-producing instruments I have just enumerated, may still serve, as I have said, for a 'practical confrontative study' and an approximate understanding of how cosmic substances of different density and vivifyingness are formed during the process of the Most Great Trogoautoegocrat from what is called the 'flow of vibrations issuing one from another,' and how they unite and separate among themselves to form large and small relatively independent concentrations, thus actualizing the common-cosmic Iraniranumange.
Moreover, you will soon be convinced of this yourself when we return to our dear Karatas and I demonstrate and explain to you, as I already promised, the significance of the principle of tuning that contemporary sound-producing instrument, the 'piano'--which, among a number of other things, I brought home with me from the surface of your planet in order to clarify experimentally, at leisure, one of its particularities that I had no time to study on the spot, and which is connected both with the strange psyche of these three-brained beings who have taken your fancy and with the vibrations of different vivifyingness engendered around them.
Now, as regards the strange psyche of your favorites, I wish to tell you about one fact I observed during my last sojourn among them, namely, that although the contemporary three-brained beings of your planet have made this 'Chinese seven-toned subdivision' the basis of all their sound-producing instruments and perceive its consequences almost daily, they are not at all inspired by this--as objectively they should be--but on the contrary, under the action of this kind of consonance, with a total lack of remorse and even with an impulse of satisfaction, they intentionally maintain in themselves the flowing of those associations that arise in their common presence in all their spiritualized parts under the influence of data crystallized in them from the consequences of the properties of that accursed organ kundabuffer.
After that practical demonstration on the piano, you will have, I am sure, not only an approximate representation of what is called the 'flow of center-of-gravity vibrations issuing one from the other and blending harmoniously,' but you will realize once more with an impulse of astonishment the extent of the weakening in the common presence of all three-brained beings, and which taken as a whole are called 'subtlety of instinct.'

We perceive the consequences daily of 7 tone scaled music, yes, and then, this tickles our fancy - not remorse and sadly, but impulsive satisfaction, yes, that's us!
May our perception of the science of music help us be balanced and aware. Ooooom.
Love n light, Teo
Where do you get all this material from, Teo?? 
, and I don't think that they are blending very harmoniously
