This piece is great fun because it is composed of lively marching music interspersed with fanfares. Here is what I did with my kindergarten and first grade age kids. I made several posters of villages - all story book type villages that belong in a make-believe world. All the kids had to do was march around the villages but whenever a fanfare played they had to hurry and get to a village. You could make it a game of sorts and if you're not at a village, you're out but I never did that. The kids thought it was fun to just listen for the fanfare and run over to a village. It's a simple exercise but helps to tune their musical ear.
Idea #2 - Yankee Doodle - This is a song with a simple verse/refrain pattern. (AB) I chose it because it is so familiar. There are a number of ways you might demonstrate form with this song. A simple idea would be to march on the verse and then play a drum on the refrain - a drum being anything you can find that you can play in a drumming fashion if you don't own drums. Or you can make up different actions for each section. You might choose to march in a line (follow the leaders style) for the A section and then each person marches anywhere they want on the refrain. Kids like to choose their own actions and be creative.
Idea #3 - Jingle Bells - Another song with a simple verse/refrain pattern. (AB) I used to set up chairs around the room with jingle bells on them. During the verse the kids were allowed to skip around the room but when the refrain began they had to sit on a chair and play their bells. Again there is no right or wrong when it comes to the actions. But there can only be two different movements - 1 for the A (verse) and the other for the B (refrain).
Idea # 4 - Folk Dancing is all about form. Simple folk dances for children have a pattern of repeated musical ideas. There is a different movement for each musical idea. Here are two familiar and popular dances for kids. Each is in the simple AB form. The ear is being trained to listen for the changes in the music.
