Equal tension strings
Can someone tell us his experience about equal tension gut strings?
The pros & cons...
Pros: none, as far as I can tell
@Amine, I agree generally with Cotton on this. But if you're into pre-Renaissance repertoire playing on a distant predecessor of the modern violin, well, maybe ...
Cotton, with equal tension and equal weight, the 4 strings will give the same note!
Amine, I suspect you may not get much experience-based feedback on ET strings on this site. ET strings (or "equal feel" if you end up on that side of this particular debate) are part of a theory of equal or greater than modern historical string tensions that require a particular setup on your violin, and are really geared towards early music practitioners playing violins in baroque or earlier style setups with the relevant bows. Although they are a very interesting avenue for musical exploration and I personally like listening to people who use them, even most 'baroque' violinists tend to use lower and graduated string tensions with wound G strings. The Gabrieli Consort and Monteverdi String Band use historical string tensions and you can find a few videos on youtube.
You forget to consider the other important factor in determining pitch: density per unit length. The strings can have the same weight but different diametre and you will get the pitches you need.
Amine, my luthier answered this question with British accent:
The practice of winding metal wire on gut strings was believed to be adopted before the year 1700 because the sound was more attractive. "Wound strings have much less stiffness than large solid core gut ones with correspondingly improved harmonicity" (according to Sir James Beament in his book "The Violin Explained").
Cotton, sorry but the pitch depends only on a)tension, and b)
Is it the case that the soundpost only exists to strengthen the violin against the extra tension caused in the treble by gut strings being more similar in weight 300 years ago?
Pah, semantics. You know what I mean.
Rocky, trust me, I learned a lot of things for my music in this forum than in the real life! So imagine if I change country :)
