NTR: Viruses Via E-mail

Forgive me for the Non-Tuning-Related ("NTR") message here, but I
thought it worth setting the record straight about one detail.

A while back somebody on the list intercepted a hoax message about a new
E-mail-conducted virus. At least two of us responded saying that it was
nothing to worry about, since a computer can't contract a virus (or do
anything AT ALL for that matter) without actually running the program that
embodies the virus, and merely reading an E-mail message can't possibly
result in your computer executing the E-mail as a program.

Well, that assumes that you don't have your E-mail program set to
blindly execute every attachment it receives WITH that E-mail. I had never
even heard of any E-mail programs that offer such a ludicrously dangerous
option, but apparently at least one does. Definitely turn that option off
if your program has it.

But as long as you don't blindly run attached files, your computer
definitely can't get a virus from merely reading E-mail.

Perhaps it's a little unfortunate that Mark didn't choose 9:7 for the
supramajor rather than 21:16. But then again, 19 doesn't really provide
for supramajors and subminors as such; it really only provides for
differences between augmented intervals and the next higher interval class.


In other words, since in 19 the 7-step interval is really an augmented
third rather than a supramajor, since it is roughly equally far above the
major third as the minor third is below it. A supramajor third would have
to be roughly half as far above the major third as the minor third is below
it. 21:16 is definitely an augmented third.

7:6, however, definitely is subminor, being about a quartertone below
the minor third. So I guess it's a little asymmetrical there.

Ah! This terminology and symmetry concerns only go so far; what
matters is that you make great music with it! I'd like to hear some
whenever you have a chance to make some.

By the way, Lydia Ayers has also worked with a Just 19-toned scale. I
don't recall the ratios off the top of my head though.
