The development of the Passione aimed at reducing the playing-in-time of traditional gut strings and to increase their tuning stability without loosing the beauty of the gut sound. The gentle processing of the gut core is key to the conservation of the ravishing beauty of gut strings’ sound. Our expertise has been developed since 1798 and has been carefully protected over generations within Pirastro’s employees.

The combination in manufacturing of modern synthetic and traditional gut technology made it possible to retain the sound beauty of gut core strings and to increase significantly the tuning stability and the break-in-time. Passione strings possess a fascinating diversity of sounds, which allows musicians to alter their tone as desired. To such an outstanding extent this is still only possible with gut core strings. The core sound is full, round and warm and has a complex overtone spectrum causing brilliance and clarity and a great power of projection.

Passione’s sound can be big and powerful as well as gentle and tender. Passione is a modern reliable gut string for the demanding violin professional. The set is well-balanced; the response is easy on all levels of the dynamic range. The accuracy of contact point is easily manageable, similar to Obligato, Wondertone Solo and Evah Pirazzi.

Gauges and technical information:

The A, D and G strings are available in five gauges with a difference of ¼ PM each. Please refer to the table below. The E string “silvery steel” is available in 25.5 and 26 and 26.7.

This plurality of gauges allows musicians to choose their preferred gauge and makes it possible to respond to the individual tension requirements of their instruments.

As a rule of thumb:

• The thicker a string is, the more powerful is the sound and the higher is the tension.
• A thinner string will produce a brighter sound, however this does not mean that the sound is weaker or looses power.

All A, D and G strings come with a ball end in order to facilitate the installation.
The E string is available with loop or ball end.

The length of the coloured peg end of the Passione G string is different than the length of the A and D strings. This is on purpose and part of the construction of the G string. The special length of the G string’s colour winding at the peg end Prevents the string from breaking in the peg box. At the latest after two to three days the stretching process will be finalized. As a result the silk winding will no longer reach over the nut. We have made numerous tests with this special G on various violins all differing in size and the string has always fitted.On some violins it takes longer, with other violins the string even fits from the beginning.
