Join Tom on a Listening Service voyage across our oceans to discover why music has long been inspired by the sea - from Sibelius and Mendelssohn to John Luther Adams and The Beatles - how have composers tried to capture the ocean in their music? Is it even possible?

Meanwhile, Tom discovers music that is literally created by the sea itself from Blackpool to the Arctic, and dives down into the sounds of coral reefs with the marine biologist Helen Scales to hear the noisy vibrant reality of life under the waves, from snapping pistol shrimps and angry damsel fish to singing whales.
