Toy Piano

4 min
Edition Juliane Klein


programme note

This piece derives of the idea of a little diamond. Not a perfect diamond but one with a lot of colour effects. Crystallographic disorders, e.g. point, line, planar and bulk defects can occur inside regularly ordered crystallographic structures and are a reason for the colour and colour effects. Elastic and plastic distortion is a reason for delocalization of the regularly ordered elements of a metallic bond. These metallic bonds - in German called metallic “fences” - and the elastic distortions are the physical reason of the vibration of the metal bars of the Toy Piano, its sound. The plastic distortions of the slightly imperfect metal bars - looking like a fence in their regular order - make the unique sound of each single pitch and special beauty of this instrument.
