I don’t know what you think of doing solo musical items in a congregational meeting. I blow hot and cold on the issue.
I used to organise a lot more solo stuff, but recently (other than Christmas and Good Friday), I can only remember doing one item in the last year.
I don’t think that there is any right or wrong about it — some like to have time to sit, listen and reflect (that’s why Good Friday gives an excellent opportunity for solos). Others would rather use the time singing with the rest of the congregation than listening to someone else doing it for them. Others are not particularly into music, and aren’t bothered either way. I’m probably a bit of the second and third group, so I need to work harder than others at encouraging those who find musical slots beneficial.
