Two different studies looked at the spread of droplets during singing. In the first study, eight professional singers sang a solo in a laboratory.
They each sang three pieces: a Japanese children’s song, the Ode an die Freude by Beethoven and La Traviata by Verdi.
Beethoven sprays the most
By far the most particles were released during the singing of the German piece: 1302 per minute. The Italian piece of music produced 1166 parts per minute, the Japanese song only 580.

In a second study, twenty singers sang a Japanese song and a piece from Beethoven’s Ninth Symphony. Then it was examined how far droplets spread.
In the Japanese song it was about 61 centimeters. In German music the droplets reached almost twice as far: up to 111 centimeters.
Hard consonants
The difference is probably because consonants in Japanese are a lot softer. Especially with loud sounds, drops are released: those who only sing ‘ah, ee, oo, eh, oh’, scatter almost no particles.
In the Netherlands it has been discouraged to sing in a choir since December 1. Maybe in the meantime members of a singing choir can practice with some Japanese children’s songs.
