Pirastro Perpetual Cello Strings

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, Pirastro concentrated on reducing the break-in time. Their 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. 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. Their musical intuition and expertise allowed them to realize this milestone in their developmental work.

Pirastro approaches 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 they had to meet were easy playability, long durability, and perfect string-to-string harmony. This new idea laid the foundation for Pirastro 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 playing.

The Perpetual standard set is tonally clear and precise with tremendous warmth. The bow response of each string is easy and direct with no delay time; even the smallest bow movements are transformed immediately into sound. For more brilliance and dynamics we also offer the Perpetual in a soloist version. The combination of its wonderfully round and full sounding A with a surprisingly small diameter soloistic D awards the player with a sound image that has incredible radiance and presence.
