Professor Christian Kähler and Dr Rainer Hain from the military university in Munich have been conducting experiments with singers and orchestral musicians to determine whether their activities can spread the Coronavirus.
The initial results from the Institute of Fluid Mechanics and Aerodynamics are encouraging.
Air was only set in motion no more than half a metre in front of the mouth, making virus spread beyond that ‘extremely unlikely’, according to the study leaders. Kähler nonetheless recommended a 1.5 metre safety cordon in a choir or church of 1.5 meters, as well as distancing between singers to prevent droplet infection.
For trumpet and trombone and euphonium, the air-motion was again half a metre. But clarinet, oboe and bassoon moved the air more than one metre and flutes reached an even greater range. The recommendation was that flutes should be played with a gauze over the outlet.
These are initial findings, translated from the German, and they are not definitive.
But they are encouraging for the eventual resumption of musical activity.
