A respiratory mask fitted with various sensors and an arduino synthesizer.
Wearing the mask and singing through it will generate a 3W drone in tune of a chosen scale.
This means that you dont have to know how to sing to be able to join the (hard)chorus, its auto tuned!
Stepping up and down the scale is controlled with a flex sensor in your hand.
The hardchorus is a workshop project. The idea is to have people join the chorus by building their own masks.
