Pirastro perpetual vs Kaplan vivo
Both strings are meant to improve clarity and projection. Which owuld be better for a soloist? Would andrea rosin and these be an overkill?
Are you a soloist?
The Kaplan Vivo certainly have some horsepower to them. But are not overly bright.
For soloists, an artistically developed bow arm is better than both options, but they could use either-and other choices-just as well.
Alex, you keep asking string questions about circumstances in which it should not be difficult to be heard over an orchestra. That suggests the issue is your tone production technique, possibly coupled to needing a better violin.
If this is not a joke, I would say the Kaplan Vivos are not on the same speaking terms with Perpetuals.
It's not overkill to use expensive strings, bow, and accessories on an expensive, quality instrument for professional playing. It is overkill if you have an ordinary, student-grade instrument
Perpetual and Kaplan Vivo are both "good" strings. If you are trying to decide between them, you'd have to try them. Andrea rosin is also "good".
I would also note to Joel's point that an expensive, quality instrument for professional playing will probably sound fine with any string that isn't an actively bad mismatch (for instance, high-tension strings on a violin that doesn't like high tension). Plenty of people who own higher-end instruments just put Dominants on them.
I'm with Lydia on the Kaplans - I did not like how they felt, nor did I like how they sounded on my violin. They felt like guitar strings to me, and made my violin sound like it was under water or something. Not a good fit.
I hate all d'Addario strings. With all that fancy technology they boast about ad nauseam, they can't seem to produce a decent product. Both their violin and guitar strings are like sandpaper under the fingers and are impossible to get a clean sound out of.
