Xylophone

What you can do here
Strike every bar with the mallet. Each of them emits a different sound. Play the xylophone by striking the bars closer to their upper ends or to their centres. Examine how the sound pitch changes with the change of the spot you hit.


How it works
The xylophone comes from a family of self-sounding instruments – the so-called idiophones. The bar, when struck, vibrates and emits a sound wave dependent on its length. The shorter the bar, the higher the pitch.


Interesting facts
The first European depiction of the xylophone can be seen in one of the woodcuts from the 1523 Dance of Death cycle by Hans Holbein the Younger.
