Music is a field of art with which each of us has had more or less contact. Music education should be provided to children from an early age – it develops their imagination, brings relaxation and influences their emotional development. One of the musical instruments proposed in music lessons is a xylophone. The sounds that children make can become familiar with the “Playing Floor” application while playing. The boards bend and make xylophone sounds when you click on them once. Multiple boards can be activated at the same time – then the sounds will be superimposed on each other. Each plank of the floor makes a different xylophone sound – can you play a tune?
