High wood

Gabrielle Hoad & Megan Calver | Clouded Border | 2022 | Work in progress - bell of an oboe

For Clouded Border, Megan Calver and I have been researching Oboe, an innovative radio-navigation system developed and deployed at Durlston during World War II. The system directed aircraft to targets in mainland Europe that were obscured by cloud or darkness.

Curious about the precise signals used, we cross-referenced a number of sources – including recordings from the Imperial War Museum and technical papers by Oboe’s inventors – to come up with a definitive score for the coded Morse sequence that would have been heard by RAF pilots in their headsets. The signalling tone was said to mimic an oboe, hence its name. We’ve now commissioned an oboist - Paul Sartin - to create and perform a new contemporary sound work for the exhibition based on this score.

The name of the musical instrument itself derives from the French haut bois or 'high wood’. We are intrigued by its correspondence to the wooden Mosquito planes chosen to carry Oboe navigation equipment. Mosquito aircraft were capable of flying at sufficient altitude to send and receive radio signals over long distances. So they too were ‘high wood’.

However Mosquitoes were too small and light to carry many bombs and so usually acted as pathfinders, dropping flares to mark the targets for the heavy bombers that followed.

Paul will perform the piece live in the exhibition space at Durlston Belvedere at 2.30pm on Saturday 24 September.
