Here are 10 things I've learned that really help a Sacrament Meeting performance.
1. Start learning the song early. Practicing the song even just a little bit for several weeks is better than just one highly concentrated shot at it.
2. During Singing Time, tell the Senior Primary kids to stand behind the little kids during the performance. I also ask for their help moving the little kids to the front.
3. Ask the Bishopric member to invite the children to come forward when it's time for them to sing. Otherwise you have some kids straggle up at the last minute.
4.. Help the kids get situated on stand. I stand in front of them and give them big smiles while I move the little ones forward and the bigger ones back.
5. Go over the words with them while helping kids move into position. I just start saying the words while I move kids around. This is especially helpful if you have Sacrament Meeting first, or if you are singing the week after Stake or General Conference. This also helps them SEE ME. Because I'm right in front of them they can't miss me and their eyes follow me while I take my place. If I just sit on the bench while they take their position and don't help them get situated, I'm just one of the crowd.
6. Sit on the front bench. Or stand up behind the front bench if it's not available.
7. Give them a BIG SMILE. And motion for them to smile. It makes a big difference in how they feel and how the audience enjoys the performance.
8. Exaggerate their entrance. Use your body and arms to help them know when to come in. Having a strong start gives them confidence to sing out.
9. Use signs to remind them of words in weak spots. Put your hand behind your ear if they aren't singing out, but use this sparingly or it looses it's effect.
10. When they're done give them a big thumbs up, a thank you and a big smile. Then motion for them to go sit down.
