A thousand-strong orchestra will be serenading world leaders attending the G7 summit as a reminder for them to 'cherish the ocean.'

Prime Ministers and presidents attending the summit, being held at the Carbis Bay Hotel on June 11-13, will be treated to a windy surprise as the Tête à Tête opera company, along with one thousand local volunteers will be performing a 'mass musical meditation on the welfare of the sea.'

Named 'Song of the Sea/Kan an Mor' he performance will look to remind those in attendance to consider how to cherish our environment and will be held on Hayle beach, directly opposite the host venue.

The socially distanced whirly tube orchestra will start with just one instrument, then become a huge crescendo of sound with all one thousand instruments before dwindling back down to silence.

The event has also been described by organisers as "a musical echo of Cornwall’s world-leading response to marine plastic pollution," as well as "a powerful metaphor for collaboration, community and climate change, offering a moment of repose, reflection and hope for the G7, for Cornwall and for the world.

The material for the tubes is polypropylene sourced by Waterhaul and is a mixture of end of life fishing net from South West ports, mainly Plymouth, as well as some other abandoned fishing lines and gear collected from the coastline at Mousehole, Porthtowan/Chapel Porth, Mawgan Porth, near Pentewan, Park Head and Bedruthan Steps.

This waste material, originally intended to be made into Waterhaul’s litterpickers, was then melted down and shredded into pellets of raw plastic in the Midlands before being transformed into whirly tubes by Techtube, a plastic fabrication company based in Sutton-in-Ashfield.

After the event they will be repurposed, leaving a collection point to be hosted by North Quay, where people can leave the plastic marine litter that they find on the beach to be taken safely away from the sea by #2MinuteBeachClean, a charity attempting to clean up the planet by promoting the idea that people should take just two minutes of their time to clean up the environment around them.

Tête à Tête are also urging the public to add their voice to this emotive message from the sea for greater care from our world leaders by uploading a short video with a message to the delegates onto social media and tagging it #SongOfTheSea @TêteàTêteOpera.
