It looks... mathematical. It also looks strikingly right, I just spend
a good quarter hour staring at the diagram and currently try to
convince my visualisation that the geometry is possible. The key points
to look out for are the diagonal lines featuring the same numbers,
vertical lines featuring series and where (_,n) changes into (n,_), to
get the mind accept the möbiusness.
I could show you why it's mirrored and twisted around the tritone using
a guitar and gnuplot, but I won't spoil the fun. Just observe that you
can easily play a flageolet on the 5th, 7th and 12th fret but not on the
6th. Western music is defined by fifth and fourths. It's all wave
mechanics, especially this darn problem of merging a linear scale to a
logarithmic one and trying to make sense while doing such an insane
