Raymond Smullyan: Famous Logician, realized that the Secret "group of Notes" is the Melody as the Dao of Daoism

You like this dude: Raymond M. Smullyan, The Tao Is Silent:
 

 
So this is precisely what I am saying. All human cultures use the Octave, Perfect Fifth and Perfect Fourth and this is what creates melodies - the "group of notes" is this secret with the Octave as the Emptiness, Yang as the Perfect Fifth and Yin as the PErfect Fourth. In alchemy we transform the yin into the yang but this process is eternal as undivided yin-yang - the Yuan Qi - so it is eternal listening to the source of the group of notes.
 
This is not a metaphor - but the literal logic of Daoism.
 
And so since Raymond M. Smullyan was a Western trained musician, he was relying on the wrong symmetric mathematics that was created from the wrong music theory. But since he trained as a musician - he realized there is a deeper secret to listening to a group of notes as a melody. That secret is the harmony of the Dao. He says it's the secret of hearing a melody instead of hearing the sounds.
