It is typically associated with the physical patterns produced through the interaction of sound waves in a medium. A simple experiment demonstrating the visualisation of cymatics can be done by sprinkling sand on a metal plate and vibrating the plate, for example by drawing a violin bow along the edge, the sand will then form itself into standing wave patterns such as simple concentric circles. The higher the frequency, the more complex the shapes produced, with certain shapes having similarities to traditional mandala designs. History of Cymatics The study of the patterns produced by vibrating bodies has a venerable history. One of the earliest to notice that an oscillating body displayed regular patterns was Galileo Galilei, who wrote in his 1632 book, "Dialogue Concerning the Two Chief World Systems": "As I was scraping a brass plate with a sharp iron chisel in order to remove some spots from it and was running the chisel rather rapidly over it, I once or twice, during many strokes, heard the plate emit a rather strong and clear whistling sound: on looking at the plate more carefully, I noticed a long row of fine streaks parallel and equidistant from one another. Scraping with the chisel over and over again, I noticed that it was only when the plate emitted this hissing noise that any marks were left upon it; when the scraping was not accompanied by this sibilant note there was not the least trace of such marks." On July 8, 1680, Robert Hooke was able to see the nodal patterns associated with the modes of vibration of glass plates. Hooke ran a bow along the edge of a glass plate covered with flour, and saw the nodal patterns emerge.[2][3] In 1787, Ernst Chladni repeated the work of Robert Hooke and published "Entdeckungen über die Theorie des Klanges" ("Discoveries in the Theory of Sound"). In this book, Chladni describes the patterns seen by placing sand on metal plates which are made to vibrate by stroking the edge of the plate with a bow. The term cymatics was coined by the Swiss scientist, Hans Jenny. It is derived from the Greek kyma (????) meaning "wave," and ta kymatika meaning "matters pertaining to waves." Cymatics was explored by Jenny in his 1967 book, Kymatik 3 of 35 11/17/2009 4:42 PM Cymatics (Applied Biophysics Aether Research Laboratory) http://sites.google.com/site/appliedbiophysicsresearch/sound/cymatics (translated Cymatics).[4] Inspired by systems theory and the work of Ernst Chladni, Jenny began an investigation of periodic phenomena but especially the visual display of sound. He used standing waves, piezoelectric amplifiers, and other methods and materials. New Discoveries with Cymatics The discovery of a breakthrough technique that involves making dolphin and whale sounds visible in water, possibly mimicking the very mechanisms that nature evolved in the cetaceans' own sound-receiving apparatus, was announced in late 2008 using a newly developed instrument, the CymaScope. A team led by Jack Kassewitz in the USA and John Stuart Reid in the UK aim to build a lexicon of cetacean In Greek, 'Aithen' means to burn or words, each word having a specific meaning and each forming shine a recognizable pattern, known as a CymaGlyph.

" The material Universe is solely made out of Aether " Influences in art Matter is made of waves Jenny's book influenced Alvin Lucier and, along with Chladni, helped lead to Lucier's composition Queen of the South. Jenny's work was also followed up by Center for Advanced Visual Studies (CAVS) founder Gyorgy Kepes at MIT. [5] His work in this area included an acoustically vibrated piece of sheet metal in which small holes had been drilled in a grid. Matter is made of waves Small flames of gas burned through these holes and thermodynamic patterns were made visible by this setup. The Greek derived word Aether is defined in the Webster Universal Dictionary as a: Based on work done in this field, photographer Alexander Lauterwasser captures imagery of water surfaces set into "hypothetical medium, supposed to fill space, motion by sound sources ranging from pure sine waves, to by means of vibrations in which light music by Ludwig van Beethoven, Karlheinz Stockhausen, and other forms of radiation are transmitted". electroacoustic group Kymatik(who often record in surround Up until the latter part of the last century the sound ambisonics), and overtone singing.

This principle has found its relevance in many scientific and engineering applications where the displacement or response of components under the influence of vibration is vital. This study presents an alternative method of determining the modal shapes on vibrating plate in addition to other existing methods like the experimental method by Ernst Chladni. Three (3) finite element solvers namely: CATIA 2017 version, ANSYS R15.0 2017 version and HYPERMESH 2016 version were employed in the modelling process of the 0.40 mm x 0.40 mm plate and simulation of corresponding mode shapes (Chladni patterns) as well as the modal frequencies using Finite Element Method (FEM). Result of modal frequency obtained from the experimental analysis agreed with the FEM simulated, with HYPERMESH generated results being the closest to the experimental values.

ChemRxiv. Preprint. https://doi.org/10.26434/chemrxiv.10255838.v1 Chemistry students are often introduced to the concept of atomic orbitals with a representation of a one-dimensional standing wave. The classic example is the harmonic frequencies which produce standing waves on a guitar string; a concept which is easily replicated in class with a length of rope. From here, students are typically exposed to a more realistic three-dimensional model, which can often be difficult to visualize. Extrapolation from a two-dimensional model, such as the vibrational modes of a drumhead, can be used to convey the standing wave concept to students more easily. We have opted to use Chladni plates which may be tuned to give a two-dimensional standing wave which serves as a cross-sectional representation of atomic orbitals. The demonstration, intended for first year chemistry students, facilitates the examination of nodal and anti-nodal regions of a Chladni figure which students can then connect to the concept of quantum mechanical parameters and their relationship to atomic orbital shape.

  • Real-Time 3D Graphic Augmentation of Therapeutic Music Sessions for People on the Autism Spectrum
    Real-time 3D Graphic Augmentation of Therapeutic Music Sessions for People on the Autism Spectrum John Joseph McGowan Submitted in partial fulfilment of the requirements of Edinburgh Napier University for the degree of Doctor of Philosophy October 2018 Declaration I, John McGowan, declare that the work contained within this thesis has not been submitted for any other degree or professional qualification. Furthermore, the thesis is the result of the student’s own independent work. Published material associated with the thesis is detailed within the section on Associate Publications. Signed: Date: 12th October 2019 J J McGowan Abstract i Abstract This thesis looks at the requirements analysis, design, development and evaluation of an application, CymaSense, as a means of improving the communicative behaviours of autistic participants through therapeutic music sessions, via the addition of a visual modality. Autism spectrum condition (ASC) is a lifelong neurodevelopmental disorder that can affect people in a number of ways, commonly through difficulties in communication. Interactive audio-visual feedback can be an effective way to enhance music therapy for people on the autism spectrum. A multi-sensory approach encourages musical engagement within clients, increasing levels of communication and social interaction beyond the sessions. Cymatics describes a resultant visualised geometry of vibration through a variety of mediums, typically through salt on a brass plate or via water. The research reported in this thesis focuses on how an interactive audio-visual application, based on Cymatics, might improve communication for people on the autism spectrum. A requirements analysis was conducted through interviews with four therapeutic music practitioners, aimed at identifying working practices with autistic clients.

  • From Hydrophonics to Interactive Sound Fountains
    From Hydrophonics to Interactive Sound Fountains Johannes Birringer From “Series One” – Open Studio Exhibition, Derby University April – May 2008. Although modest and seemingly unspectacular, Caroline Locke’s phrase “seeing sound” – a phrase she used to describe her interests in creating sculptural sound-performance works when I first met her in 2004 – has stuck with me. It is an odd paradox, but one that has gained resonance in recent years as we have moved along with the scientific and technological advances in a culture obsessed with data visualizations and location mapping. Today’s ultrasonic medical scanning of our arterial blood flow allows us to peer inside ourselves, so to speak. We depend on x-ray vision to diagnose a fracture of our bones, and neurologists look into our brains to pinpoint areas responsible for thoughts, feelings, and actions. Sound and vision are two closely related sensory registers, yet we do not commonly think of sight being audible, and sound being visible. We do not see with our ears, we use them to listen to the wind as we go forth in the world, as the anthropologist Tim Ingold once suggested, noting that wind and breath are intimately related in the continuous movement of inhalation and exhalation that is fundamental to life and being.1 1 Cf. Tim Ingold, “Against Soundscape,” in Angus Carlyle (ed.), Autumn. Leaves: Sound and the Environment in Artistic Practice (Paris: Double Entendre, 2007), pp. 10-13. 2 Even though my immediate contact with Caroline Locke’s artistic creativity and collaborative ventures was limited to a brief two-year period (2004-05), I propose to reflect here on her major performance installation Hydrophonics (2005) and her on-going preoccupation with water and sound, attempting to sketch a particular collaborative and interactive trajectory in the various manifestations of her artistic project.

  • Wave Goodbye to Sound Waves
    www.cymascope.com Wave Goodbye to Sound Waves Wave Goodbye to Sound Waves John Stuart Reid Sound is a wave, right? If you share this commonly held belief it is probably because everything you have ever read or been told about sound, whether from high school, popular science books or university courses has said so. And yet, if our eyes could see sound, we would not see waves wiggling their way through the air. Instead, we would see something quite surprising, as you will soon learn. So how did the popular belief in ‘sound waves’ begin? The confusion may have begun with German musician and physicist Ernst Chladni (1756-1827), sometimes described as ‘the father of acoustics.’ Chladni was inspired by the earlier work of English scientist Robert Hooke (1635–1703), who made contributions to many fields including mathematics, optics, mechanics, architecture and astronomy. In 1680 Hooke devised an apparatus consisting of a glass plate covered with flour that he ‘played’ with a violin bow. He was fascinated by the resulting patterns. Around 1800 this phenomenon Ernst Chladni was further explored by Ernst Robert Hooke Chladni, who used a brass plate and sand. Brass is a highly resonant metal and the bell-like sounds he created resulted in the sand grains organizing themselves into complex geometric patterns. These archetypal patterns are now referred to as ‘Chladni Figures,’ although the originator of the invention was actually Hooke. Chladni demonstrated this seemingly magical phenomenon all over Europe and he even had an audience with Napoleon. The French leader was so impressed that he sponsored a competition with The French Academy of Sciences in order to acquire an explanation as to the mechanism behind the sand patterns.

  • Firmament of Sound
    Firmament of Sound Before there were eyes to see when a vast darkness still permeated the void, All rested beneath a firmament of Sound. I stare into the primal pool breath ripples the water and light appears –as if from within– a raiment of pastel profusion barely the faintest hint of definition. I open myself and eyes appear –as if from within– so that I might see myself apart from the landscape, a part of the landscape– my original face peering out of the darkness, peering into the void. Without fear; without pain; no sharp edges; no hard places; no borders. Nothing to recoil from no need for protection no need for rejection– no separation. I raise my voice and Behold! I Create my own personal playground, a universe of figure, form and motion arising from my impetuous imagination. © 2009, Jeff Volk Autumn 2010 FROM VIBRATION TO MANIFESTATION: Assuming our Rightful Place in Creation All is vibration! ––Novalis Editor’s Note: The following article builds on Cymatics: Insights into the Invisible World of Sound, published in the Summer 2009 issue of The Quester.

  • CHLADNI PATTERNS by Tom and Joseph Irvine
    CHLADNI PATTERNS By Tom and Joseph Irvine September 18, 2000 Email: [email protected] ______________________________________________________________________ HISTORICAL BACKGROUND Ernst Chladni (1756-1827) was a German physicist who performed experimental studies of vibrating plates. Specifically, he spread fine sand over metal or glass plates. He then excited the fundamental natural frequency of the plate by stroking a violin bow across one of its edges. As a result, a standing wave formed in the plate. A standing wave has "anti-nodes" where the maximum displacement occurs. A standing wave also has "nodes" where no displacement occurs. For a vibrating plate, the nodes occur along "nodal lines." In Chladni's experiment, the sand grains responded to the excitation by migrating to the nodal lines of the plates. The grains thus traced the nodal line pattern. Sophie Germain (1776-1831) derived mathematical equations to describe Chladni's experiments. She published these equations in Memoir on the Vibrations of Elastic Plates. Jules Lissajous (1822-1880) performed further vibration research using Chladni's test methods. THEORY Elastic plates have numerous natural frequencies. The lowest natural frequency is called the fundamental natural frequency. The fundamental frequency is usually the dominant frequency. Each natural frequency has a corresponding "mode." The mode is defined in terms of its nodal line pattern. Each mode has a unique pattern. Points on opposite sides of a nodal line vibrate "180 degrees out-of-phase." Stroking a plate with a violin bow may excite several natural frequencies, thus complicating the experiment. Again, the response will usually be dominated by the fundamental mode. 1 The higher modes can be individually excited, to some extent, by stroking the plate at different edge locations.
