The Association of British Choral Directors have published a research paper on the impact of the COVID 19 virus on choral activity in the UK, prepared by Professor Martin Ashley, an ABCD trustee, provides a survey of research into the current thinking about how choirs and conductors might resume rehearsing and performing in the future.

American Choral Directors Association (ACDA) released guidance and a statement of support for choral singing and study during the COVID-19 pandemic on June 15. HERE


Provisional research results released about various types of masks HERE

Freiburg University of Music have published Risk assessment of coronavirus infection in the field of music – latest update 17 July 2020 HERE

A number of performing arts organizations have joined forces to commission a study on the effects of COVID-19 on the return to the rehearsal hall. Most up to date results can be found HERE

A UK study will explore whether singing and the playing of woodwind and brass instruments produces more respiratory particles than speaking HERE

In the Netherlands they have gathered a consortium that would like to encourage research specifically on the effects of music-making. This research project initiated by the Rotterdam Philharmonic Orchestra (RPhO) and supported by all major Dutch orchestral and choral associations is carried out by Delft University of Technology (TU Delft). The aim is to publish and review the different articles and come up with clear and scientific based advice for singers and wind musicians. See https://www.virmus.nl/ where they have started collecting existing research, including contradicting research about aerosols.

They also did an interesting Study in the Netherlands on ventilation and singing -> here.

In Austria the Wiener Philharmoniker also did a similar study here The Chorverband Österreich commissioned a study with the Vienna university on aerosoles and singing, see -> here. They only observed the emission of aerosols, not their distribution in a room over time and not the role they can play in infections, but they showed with the pictures they made that aerosoles are not distributed over a significant distance. They recommend wearing facemasks for singing.

In Norway, Thomas Caplin is conducting a quantitative research project, gathering data from some choirs in May and June after the start of rehearsals at the end of April, with the aim to prove that it is safe to start singing together. / The Norwegian Choral Association is doing a research project in cooperation with a research institute and the Norwegian Institute of Public Health, where they will measure droplets and micro-droplets during singing compared to talking.

It also seems there is a study on aerosols and singing done by a university in Trondheim, and in Sweden a university in Lund is doing similar research.

In Canada research was started with the aim of assessing whether singing in group sis a super-spreader activity, see here
