Shakespeare said “all the world’s a stage and all the men and women merely players” and for the Cornwall factory of European Springs & Pressings, this couldn’t be more true.

The National Theatre is staging Shakespeare’s Macbeth and approached the Redruth factory to develop springs that enhanced the sound production of the performance.

Simon Allen, instrument maker and sonic bricolage for Macbeth at the National Theatre, said: “We were looking to procure some large tension and compression springs to use as musical instruments, played on stage by two professional musicians. I approached European Springs & Pressings with the need to develop a bespoke solution.

"Built into the infrastructure of the stage set, the springs are struck, bowed and scraped with amplification. Although there are instances of car springs and extension springs being used for sound effects, bowing springs is a rarity; and with the right specifications we’d achieve a unique sound quality.”

Michael Gibbs, managing director of the Cornish factory, said: “Our springs and wire forms are used across multiple industries for multiple purposes from automotive to shipping, oil rigs to the medical industry but this really is a first.

"We’ve had springs featured in the windows of Liberty of London, we’ve been part of art installations and we’ve formed part of the architecture across key landmarks but being used for sound is a whole new world of productivity. The spring really is the most versatile of products and its engineering is at the heart of so many sectors.”
