Imagine you are near the ocean.
What does the air feel like?
Are you on the shore, in the water, out at sea?
Create the sound of the water with only your voice.
Allow your breath to become the waves. 
How does the water sound as it meets the shore?
One wave after another. 
Try this a few times. 

Then record your ocean sounds.
Use your phone as a recording device, with as little background noise as possible.
Send your sound recordings to: saythesea@gmail.com
Consider including your name or location as a title.

The recordings will form a chorus, a collective body of sound.
