true in that a couple of his pieces do make use of Fib/Phi but that was
the exception rather than the rule in Bartok's work
actually, it was Lendvai's 'analysis' which have been discounted by
Somfai, Tatlow and Griffiths as being dubious
0.6180340 is an *inverse* ratio and not the actual ratio of phi
which is 1.61803399
and hence is NOT the number the fibonacci series converges to
take any two numbers
for example: 7 and 9
sum them
then keep adding that sum to the prior number in the series
7+9=16
16+9=25
.../...
1186+1919=3105
until you get far into the series
say to about 3105
divide that number by 1919
you get 1.618030224
which as you can see starts to look a lot like phi which calculated to 20 places is
**1.61803398874989484820...**
