This single chime bar is a little like the glockenspiel. It is metal and produce a bell-like sound when beaten. This can be used to create a drone or for contrasting effect (low and high, fast and slow, long and short). In addition, these bars can be easily used by the teacher to encourage children to walk slowly or quickly, because they are so easy to hold and move around. Very versatile! This is sold individually and comes with 1 beater.
