Rita plays a small musical instrument that is made of light-yellow metal, and can give a loud, bright sound when she blows into it. People have used instruments like this for many centuries ~ in armies for instance, when they needed to send a clear signal 'far and wide' in the times before we had radio; and to draw people's attention when something important was happening (like a mail-coach coming into a town, or a king or queen going into a building). In fact, Rita usually plays her instrument quietly, indoors, in a jazz group.What instrument does she play?
