My first church solo was at my cousin's missionary farewell; I was six-years-old. It's been probably about 5 years since my last solo in church. That's the worst part of my callings over the last few years. Nobody thinks of asking me to sing other than in the choir. I think they just assume I'm too busy - or that I am at the pulpit enough already.
Otoh, I've been in small branches and groups (and an occasional ward) where I felt like I was singing a solo - and my kids have mentioned numerous times that they also feel like I am singing a solo. I don't do quiet singing.
With all of that background, my favorite musical experiences at church have been: 1) sitting next to a bishop who couldn't carry a tune in a bucket but sang with all his heart, nevertheless; 2) singing in a ward choir with a sister who was totally tone deaf, knew it, but still loved music enough to want to praise God through song.
Truly, there is power and beauty in making a joyful noise unto the Lord.
