Materials are all around us, they make up everything you can see and touch. Some have some particularly amazing properties and can make very different sounds. Listen carefully to the Minutes and see if you can hear how materials make different sounds. Are the sounds soft or harsh, do they ring on or stop straight away? Materials may be used because of their particular acoustic properties (how they sound).
