Solfeggio Frequencies- maths and music

I have been trying to think holistically about my collection, thinking about the aesthetic, mood, imagery and all that would be associated with the whole shebang
So here I have searched for music and maths- therefore Pythagoras- therefore found this little bit of info...


"According to the myth, Pythagoras was walking past a blacksmiths, listening to the sound of the hammers on the anvils.  After a while, he realised that all but one of the hammers were sounding in harmony.  Curious as to the reason, Pythagoras made a thorough examination of the hammers and discovered that when their masses were simple ratios i.e. 2:1 or 4:1, then the respective notes produced were in harmony.  On the other hand, the mass of the hammer producing the discordant note wasn't in a simple ratio with any of the other hammers."  (http://library.thinkquest.org/18160/mathmus.htm)


then a comment on one of the numerous videos on Youtube related to Pythagoras and Music mentioned that he used simple solfeggio frequencies so here is some music apparently based on solfeggio frequencies...

It could be interesting to mix this perhaps with some more obviously natural sounds or a rhythm, I am not sure, that is not really my expertise, but, i have learnt something new today!
