Each elementary class has music three 45 minute class meetings every three weeks, in groups ranging from 10 to 30 children. These classes develop both skill and understanding in the basic elements of music via experiences in body percussion, speech, singing, movement, folk dance, games, drama, and the playing of pitched and unpitched percussion instruments. Within any one class, the activities might be mixed, i.e., beginning with a circle dance, playing a game, working with a poem, adding instruments, creating movement and gesture that act out the text, etc. Each of the media is a strand within itself with its own sequence of development. Rather than spend two months on singing alone, two months on folk dance, etc., the strands develop side-by-side, with the teachers keeping track of each to form the overall design of the year.
