The sounds of the estuary

Last Saturday, July 15, we completed the first sound collection tour for Los sonidos del estuario, by our resident artist Armando Román, at the Santa Ana Environmental Center of the Julio Enrique Monagas National Park. An estuarine shoutout to those who accompanied us!

Los sonidos del estuario is a project of memory and sound documentation. Part of the creative process consists of three tours, where the everyday sounds of various localities located within the estuary and its watershed will be recorded. These recordings, and the experiences embodied in them, will be the basis of a sound map that will be part of the atlas of the Estuary. There are still spaces for the tours that will take place on July 23 and 27, from 8:00 a.m. to 10:00 a.m., in the Parque Central and the Piñones State Forest, respectively.

Sign up for one of the tours today, in
