Auscultation: Tin Cry by Ana Gnjatović

for accordion solo
dedicated to Vladimir Blagojević

Some metals such as tin, indium, gallium, zinc, and I think it is similar with people too, emit a certain silent crackling sound when they are folded – tin cry. The crackling sound is the result of the change in the crystal structure of the metal: under the influence of mechanical force a large number of atoms move at a high speed in the same direction starting a sound wave. It is possible to restore the original crystal structure of the metal by melting it.
