Pirastro describes their Pirazzi Platinum E as follows: E-platinum: While developing our platinum-coated violin E-string we have consistently received positive assessments that our new Platinum E-string allows for new dimensions in violin playing. This new Platinum-E provides the violinist with an immense abundance of sound colors, an overtone-rich radiance to its large warm core tone, and a wide sound projection. It has also been assessed that the sound character of our Platinum E-string exerts a "suggestive force" and "Just listen! This E is undoubtedly the new benchmark!" With our new Platinum E-string, the transitions from the A to the E are designed to be effortless without any breaks. This coupled with the perfect response of our Platinum-E helps create an experience of new freedom in the sound design.
The surface of the platinum coating provides the pleasant feeling of stability under the fingers of the left hand, which greatly benefits changes in position and vibrato.
