Old MacDonald Had a Farm

This morning, Sophie (6 years old) is playing school with an assortment of dolls and stuffed animals all lined up on an easy chair; she's teaching them to sing Old MacDonald Had a Farm. She has sung through the song quite a few times and sometimes the stuffed animals are used to represent the animals on Old MacDonald's farm. Kids like imaginative play, of course, and it's pretty common to see them imitating adult roles (parents and teachers). This is a great song, at any rate, with some complex fast rhythms and simple pentatonic melodic patterns. Other environments could be represented by changing the person (Old MacDonald) and the place (the farm). Children could also draw pictures of the various environments/habitats developed. A single chord and/or rhythmic patterns could accompany the entire song.
