New orchestral strings from Pirastro & Daddario

[Dave Whitla]

Does anyone know what the different tensions are for Passione, Deluxe and Kaplan? With all the different gauges it's hard to compare like with like.

I'm very interested in your comment that the Passiones felt a bit "loose," Ken, because that's exactly what I'm feeling right now with them on my bass. But because I'm playing it in after a long restoration I'm not sure whether what I'm feeling is caused by strings or bass (or a bit of both)...

I don't have any numbers for the tensions but as for feel I can comment. Tightest was Deluxe, and the Passiones and Kaplans were close. Maybe the Passiones were looser but thicker feeling. I have a set here of each so I could measure them but the Passione set I have has a stark E. Maybe I have an unopened set of them as well. Tension and thickness are not consistent for comparisons.

Indeed. Because of the internal construction of a string, the thickness and type of outer wrap, and the amount of damping material added, there is not any direct correlation between a string's overall diameter and the tension required for pitch.

If anybody has the means, and would care to take the time and publish the findings, whether by direct observation with a tension scale, or by deduction knowing the weight of the speaking length of a string, to find out what the tension of any given Pirastro string is, I'd be interested, because they are known for not quoting or publishing their tensions beyond the traditional light-medium-heavy generalizations. The only comments I have ever been able to find out in cyberspace regarding the relative tension of Pirastro strings are anecdotal observations like Ken's for the Passiones, and several others in different contexts have put Jazzers about midway between Spiro S42 Weich and S42 Mittel.

Following on from that, does actual tension (as measured on scale in lbs or kg) translate directly to the string feeling tight or loose, or is that feeling more abstract, like the relationship between balance and weight of bows?

I have played several basses with the same strings on them. They all feel different. So, I think the bass has more to do with the tension than the string specs in that regard.

Tailpiece angle, after length, string length, bridge height, nut height, fingerboard camber, neck strength, etc., all have something to do with the tension of your bass. I never go by numbers published on string tension other than maybe one compared to another. Once on a bass, then you can see how it feels. Belcantos on my Marconcini feel different than on my Bollbach Lion or Halle Tarr or any other bass. Same strings, different basses, different tensions!

Ken, what are the different mensures on these basses? Even 1/2 inch difference in mensure will have a noticable effect on the tension, as tension varies not directly, but as the square of the scale length.

And as you say, the setup on everything from the nut to the endpin and everything in between, including camber, can make a string feel different.

41-42" on average but it is not just the length as I can have a 41 tight and a 41 looser. It is all things combined.
