Pirastro Perpetual cello steel string A STEEL/CHROME STEEL MEDIUM

Features

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.

Set

• Medium Set

The Perpetual medium 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.

• Soloist Set

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.

• Edition Set

As a musician put it, the Perpetual Edition are the most power-packed strings in our program. Tone by tone the shine of this new string radiates into the room without sounding metallic or sharp. Like having a palette in their hands, the Perpetual Edition provides the musicians with every tonal color from a focused bright sound to a room filling warmth which is like a hug for the music enthusiast. With their sonority, volume, and flexibility the new Perpetual Edition fulfills the players’ desire for projection in an impressive way while maintaining an inspiring light playability. The Perpetual Edition strings offer an exceptional nice bow resistance which results in a very fast and direct response especially on the lower strings.

Sizes

Perpetual strings are available in 4/4.

Tailpiece Options

All strings have a ball-end.

Variations

• Strong G & C

With their increased tension the Perpetual Strong G & C produce a very clear tone and enormous volume.

• Cadenza G & C

Due to their lower tension the Perpetual Cadenza G & C noticeably relieve pressure on the cello which can allow it to open up and unfold freely. This also allows the A & D strings to vibrate very easily gaining presence while maintaining the basic sound characteristic which is dynamic and warm. The Perpetual Cadenza G & C are suitable for older Italian as well as new instruments and harmonize wonderfully with the Perpetual A & D as well as other Pirastro cello strings.
