Web Curios directs our attention to an engrossing tool that explores planar percussion, allowing one to experiment with different drums and hear and explore the sonic output in great detail. With Eigendrum (see also) can also outline their own drum and listen to the acoustics, no matter how implausible, with visualisations of the reverb and fade and mallet. The intersection of maths and music, the sound of a standing wave across a bounded surface is −∇²u = ฮปu, u being the edge where it zeroes out and lambda wave length. Most planes however are eigenvalues and do not follow the formula and must be solved numerically, scaled by inputs—in the case of one’s own creations. Bang a gong and do let us know what you discover.
