Recordings of bygone days on the streets of Hà Nội, including train bells, ancient songs and Ca Trù (ceremonial singing) will resound again for the first time in an event called Hà Nội Soundwalk on April 13.
Participants joining the walk will start from the Hà Nội Cathedral and stroll through the old streets of Hàng Gai, Hàng Vải, and Bát Đàn for 60-90 minutes.
With the aid of their smart phones and headphones they can choose which parts of the city to discover.
As walkers move from one place to the next the sounds they hear will change.
Recordings include people in the past talking about places on the route, a radio broadcast evoking a bygone era, a creaking rickshaw, a train passing or the performance of long-forgotten music.
The event is part of the ongoing 2013 Hà Nội Sound Stuff Festival, and Locative Audio project taking place in 11 cities around the world including Virginia (US), Avignon ( France ) and Oxford (UK).
Trí Minh, founder and coordinator of Sound Stuff Festival, said that all recordings and images of the walk will be sent to Barcelona, Spain, the centre of the Locative Audio project.
The sounds once familiar to Hanoians are expected to receive much attention from people, especially the youth, therefore boosting the preservation of cultural values, Minh added.
