HOW IT WORKS?
By hitting a triangle you cause acoustic disruptions, which in turn cause vibrations transported by air particles. This creates an acoustic wave that depends on triangle’s shape and size. The greater the wave’s frequency is, the higher sound you will hear. The greater the wave intensity is, the louder the sound will be.
HOW IT INFLUENCES CHILD’S DEVELOPMENT?
The development of music on child’s development is priceless and the stimulation of hearing functions is favourable for creation of new nerve connections. Playing instruments brings not only satisfaction, but also trains movement co-ordination, motor skills, attentiveness, and creative thinking. Playing triangles are widely used during kindergarten and early school music and rhythm lessons.
The device located on playgrounds is also a great fun and opportunity to creatively spend time on fresh air.
