Starting music classes with greeting or hello songs help establish routine for your students, especially the younger ones. I loved starting my classes with this little ditty that your kinders and first graders will want to sing over and over. It became so much a part of my routine that the students would get a little perturbed if I left it out for some reason! The words and lyrics are such that you can incorporate each child's name and improvise to fit your particular situation. Classroom teachers can use it as well, substituting their class names for the word "music".
