pentasystem

Apparently the folks at pentasystem think they have a patent on 5 string
guitars, or on 5 string guitars tuned in fifths. The level of pseudo
scientific nonsense there is astounding. See for yourself. It is
hilarious. In their latest ad campaign, they promise to prosecute to the
full extent of the law anyone selling a 5 string guitar! They also
assert that the new theory of music propounded by their founder could be
so revolutionary that a Nobel Peace Prize may be in order.

From the pentasystem website (the page that explains that investment may
bring untold profits):

In a nutshell, music has been improved through the Maestro's
methodology by diminishing dissonance ratios across the board up to
97%.

Get in on the future. Understand Pentasystem.

Dang, wish I'D figured out how to do that! Those pesky dissonance
ratios never did want to go that low for me. Guess I'll quit now,
and bow to Maestro Alex Gregory.

Though, we're told that it could take time before "the idea of the
Pentasystem enters the collective mainframe." Dang, where DID I leave
my collective mainframe?

Sorry, I couldn't resist a quote from
http://www.pentasystem.com/index2.html:

"The underlying master mathematical equation of 5 strings tuned in
fifths creates an unthinkable consonance of 97%.
Such consonance is the consequence (via the master mathematical
equation) of the 11 known harmonics (dimensions/frequencies within which
a single string vibrates) being aligned in such a manner that they
cannot conflict.
The master mathematical equation occurred as a consequence of my adding
a scalar view (through the 7 new dimensions of a major scale) to the
natural harmonics concept that Helmholtz had previously viewed (in sonic
physics) as the 4 dimensional proposition of a major triad chord. 4 + 7
= 11."

That about says it.
