Thread different bells on pipe cleaners. Feel free to use different numbers of bells on the pipe cleaners. Bend the pipe cleaners around the brushes. It is also possible to glue the pipe cleaners to the brushes.
Ask the children to paint different things at different speeds. This will bring out the sounds. What does it sound like if you paint a circle versus a square. Ask the children to paint as it sounds and let them discover what is happening. The older children can paint blind. Attach different numbers of bells to the brushes – from just one to many.
