Enlist the help of the pianist/organist or go to the piano yourself and have the children gather around you there.
Music has a lot to teach us about how to get along with one another. We can play one musical note all by itself and it sounds pretty. (Strike "C" and stop.) But if we play that one note over and over, we will get tired of it. (Strike "C" repetitively.) That poor, lonely note needs some company. Suppose we add another note. (Strike "C" and "E" together a few times and hold for a moment.) Hey, that's kind of nice! That lonely note is not alone anymore and those two notes sound good together.
