"Now consider which is a closer examination of man, his name or his similitude? The name for man varies in different lands, and the form is mutated only by death. And if the poet acts through the senses by way of the ear, the painter [does so] by way of the more worthy sense of the eye. By these [comparisons] I only wish for a good painter to figure the fury of a battle, and for the poet to write something about it, and for both [of these battles] to be put before the public. You will see which will stop more viewers, which they will consider longer, which will be give more praise, and will satisfy more. Certainly the painting, a great deal more useful and beautiful, will please more." - Leonardo da Vinci
"Cymatics (from Greek: κῦμα "wave") is the study of visible sound and vibration, a subset of modal phenomena. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid. Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency.
The apparatus employed can be simple, such as the old Chinese spouting bowl, or Chinese singing fountain, in which copper handles are rubbed and cause the copper bottom elements to vibrate. Other examples include the Chladni Plate and the CymaScope." - Link

It's thought that the carvings at Rosslyn Chapel demonstrate Cymantics
"Many of us like to visit the ruins of ancient monuments and temples, trying to picture what went on at these places. But it tends to be a silent movie running in our minds. Fortunately, archaeologists are at last beginning to realise that ancient people had ears, and the various soundtracks of antiquity are beginning to be investigated.
The term “archaeoacoustics” simply means the study of sound in archaeological contexts. There are two basic ways this can be done, by exploring natural sounds and acoustics at monuments and other sites, or by investigating and measuring the acoustic parameters of a place by use of electronic instrumentation."
