"Per gauge the tension alters by 10%" is what the Pirastro website
says. You may enjoy a visit to their site to read some of the
qualities and characteristics they give for their selection of
strings.

Hi Ellen,
what I mean is, for instance the Jargar G and C
strings are steel and the Belcanto G and C are ropecore. Do these
materials have a difference in tension?

Re: re: ropecore

The "rope" refers to the way in which the metal is wound within the
string. Steel cores (usually thin fibers of roped or spiraled steel)
are wrapped with a variety of metals such as aluminum, chrome steel,
tungsten, silver and most recently, titanium.

Re: re: ropecore

I'd like to be able to answer your question, but the string
companies haven't been particularly helpful in this endeavor. Having
checked with my engineer, he proposed the notion that numbers don't
necessarily MEAN much to the average bear. And trying to use
information without understanding what it all means can be as
dangerous as not having the information in the first place. For
example the Pirastro Oliv strings don't come in three tension names;
they give actual numbers. If you order an A string and receive it in
the mail with a number on it, do you know if it's light, medium or
heavy tension? Nope. Not unless you're looking at three different A
strings with three different numbers on them. If it says Light,
Medium, Heavy, you know.
However, if you have a string and
you want to try one of different tension, you haven't got a clue
which ones fall into what range. I see the merit for a comparative
chart.
That said, keep in mind Jargar steel strings come in
three tensions. I cannot obtain the relevant numbers for you, though
I seem to recall someone posting a chart once which had a lot of
tensions listed. Belcanto, on the other hand, are available in only
one tension. I didn't realize this until trying to order a Forte and
I was told it doesn't exist. Maybe it's just the Gold series -- not
sure.
Maybe one of the string expert guys can help you out.
For more interesting reading from the string sites, check out
www.thomastik.com It really is sort of neat to see what the
companies say about their strings. They will readily talk about
cores and windings, but nowhere can I find them -- any of them --
willing to discuss tension other than the reference to the fact
strings come in three tensions. Diameter/gauge is another statistic
you tend to see more for violin strings than you do cello. I tend to
agree that some of this empirical information, to the layperson,
isn't particularly helpful.
If you do try some of the heavy
tension strings, make sure, if your cello has fine tuners, it can
accommodate the rather fat string & winding. I know you didn't
ask this question, but a lot of people are reading these posts and
any tidbits that show up tangentially are of interest to some folks.
