A few chime bars with different tones and piano accompaniment is all it takes to create a moment of exploration and improvisation. First the children explored the sound possibilities of the chime bars. The pianist played an improvisation with notes corresponding with the chime bars. Although an improvisation the children were able to detect the underlying rhythmical structure. It was interesting to hear that after a while they synchronised their playing with the rhythm of the piano. Time – the allowed length of playing time – was essential. A nice moment to see that the children were able to play their chime bars and listen to the piano at the same time!
