When I was a young child, I was part of a very small choir at our church called the Seraph choir. Four little girls with older siblings who were a part of the regular children and youth choir. Both choirs met on Saturday mornings (those were the days), and we would learn new music and generally work on our music skills.
At one point our choir director (the assistant organist at our church) told us that she noticed on Sunday mornings, as she processed into the sanctuary with the choir, that we (us four little girls) were not singing along with the congregational hymns.
To encourage us to sing with the congregation, she started teaching us every Saturday morning the hymns that we would sing the next morning in worship. I am pretty sure that this one simple addition to our very simple children’s choir experience deeply affected my life. It developed my love not just for hymns but for congregational singing. It exposed me to some of the classic melodies of the Christian tradition as well as some of the most essential theological vocabulary of the faith. All starting at 6 years old.
