Ensure a staff member is present on the other end to check that the audience can see and hear you properly and facilitate interaction.

Check your audio levels in Zoom settings ( or another application) to ensure your sounds do not distort at high levels. Also, ensure you have enabled original sound if using backing tracks.

If using a speaker to play backing tracks, see if it has a base mode, as Zoom sometimes has difficulty dealing with high frequencies, and this can help reduce this issue.

You can test your sound set-up by recording yourself performing and then listening to it back.

Use microphones and Internet cables for enhanced quality

Remember, a virtual concert doesn't have to be an impersonal one. You can converse with your audience, get them to introduce themselves, join in with clapping and singing and share stories.
