About Pirastro Perpetual Cello Strings

Our engineers were faced with the challenge of developing a string using ground-breaking construction and superior material composition, while creating the machines required to achieve this. Our musical intuition and expertise allowed us to realize this milestone in our developmental work.

We approached the field of violoncello strings from an entirely new perspective: being able to forget your surroundings and focus on playing is what inspires and comforts a cellist. Therefore the key parameters we had to meet were easy playability, long durability, and perfect string-to-string harmony.

This new idea laid the foundation for us to make changes to the materials and processing techniques so that the strings acquired a further tonal dimension. This new dimension opens up the instrument to its full tonal colors and grants musicians the technical freedom to fully focus on their play.

Perpetual strings are characterized by great flexibility and an extraordinary tonal spectrum: from a sweet, warm tone to sheer endless power – everything is possible. The sound is like a large house with plenty of room for individual design. At the same time the tone is focused and clear, the most delicate touches are instantly audible and the base warmth always present. The natural qualities and timbre of each cello are enhanced by the strings’ great dynamics and intensity.

During the development we concentrated on reducing the break-in time. Our technicians did an impressive amount of research and analysis to develop a device for measuring the settling-in time, so each individual string can be tuned and brought to pitch before dispatch. This enables the materials used in the string to adjust and settle which significantly reduces the break-in time.
