Children can now sing and play musical instruments indoors and outdoors in groups of no more than ten.
That guidance came into effect on Wednesday 24 February. They need to have a responsible adult present.
Adults will be able to do the same from Monday 1 March, but only outdoors.
The government says children have been allowed to sing and play brass and woodwind music earlier than adults to support students' educational wellbeing.
"Islanders are reminded that physical distancing should be kept to two metres at all times, ventilation should be maximised indoors, no sessions should last longer than 30 minutes, and no alcohol should be consumed by adults during the sessions. When performing outdoors, spectators and crowds should be prevented.
"This guidance means the activities can take place safely with a reduced risk of COVID transmission, but the risk has not gone away. Islanders who are at higher risk should always consider any group activity in light of their personal risk of COVID-19, even if they have received a dose of the vaccine." - Dr. Ivan Muscat, Deputy Medical Officer of Health.
STAC will monitor the impact of these changes to consider whether to relax them further or tighten them again.
"We have reached a good point in our COVID-19 recovery for us to be able to relax these restrictions. Music plays an important role in many people’s wellbeing and social connectivity, so it is fantastic that we can give Islanders the chance to meet for this reason again.
"We will be reviewing the guidance frequently, against the latest data and it is hoped we can allow further easing of restrictions going forward. This past year has been tough on many children and young people and I’m sure it has been welcome news that music and singing can resume." - Deputy Richard Renouf, Health Minister.
