Luthiers still use Chladni figures in the design and construction of acoustic instruments such as violins, guitars, and cellos. The technique invented by the German physicist and musician Ernst Chladni (1756–1827) shows the modes of vibration under forcing. The backplate of the instrument is covered with flour or sand, and bowed until it reached resonance. The grains move and concentrate along the nodal lines where the surface is still, outlining the vibrational modes. A similar technique can be used for quality control of membranes of suspended two-dimensional materials, like graphene. Small imperfections deform the nodal lines for the higher modes. Their study is crucial for reproducible fabrication and applications.
