The Pirastro Perpetual cello string set was developed using ground-breaking construction and superior material composition to create strings with easy playability, long durability and perfect string-to-string harmony. Perpetual cello strings open up the instrument to its full tonal palette and grants musicians the technical freedom to fully focus on their playing. At the same time, these cello strings present a tone that is focused and clear with the most delicate touches and are instantly audible with the base warmth always present. The natural qualities and timbre of each cello are enhanced by the strings’ great dynamics and intensity. Pirastro Perpetual cello strings were also created with a reduced the break-in time, so each individual string can be tuned and brought to pitch. This enables the materials used in the string to adjust and settle which significantly reduces the break-in time.
