Sound Design Founders of the Theatre

The Theatre’s Contribution to Sound Design

As with any human discipline or industry, sound design as a practice and art form developed collectively over time, spurred on by the contributions of many and the striking visions and passion of leaders in the field. Below are two major contributors to the world of sound design as we know it today: Dan Dugan and Charlie Richmond. Both arose within the theatre world and created solutions to problems they faced – resulting in internationally respected products that we use today. Much of the major building blocks and tools used in sound design, live and in the studio, developed in the 1960s and 1970s,  and in this era these two sound founders began to make waves.

Dan Dugan

Dan Dugan, an American inventor, audio engineer, and sound recordist was born March 20, 1943. As a young man, 24, he began working in theater sound for the San Diego National Shakespeare Festival and the American conservatory. In 1968 the term “Sound Designer” was created to explain Dugan’s efforts. His first major contribution to sound design, aside from giving a reason for the term “sound designer” to exist, is specifically relevant to live performance – the “automatic microphone mixer,” known as the automixer, such below through several generations of production.

As a sound pioneer, Dan Dugan realized early in his career that he needed to work for and by himself to solve the problems he encountered – new problems were occurring in real time. As reported by Sound and Video Contractor in “AV Industry Icons” 2006, Dugan states: “I realized I had to work for myself … so I built my own studio. It was one of those gigs in ’68 or ’69 that sparked the invention of the automatic mic mixer.” It was the frustration with feedback and noise problems that arise from using multiple microphones in a singular live setting, such as a theatre stage, that gave rise to his experimentations to improve live sound and the ability to design sound without sonic flaws. The two most important problems to solve specifically were one, reducing the amplified noise contributed by multiple microphones that pick up ambient noise and, two, eliminating the feedback created with multiple actors/microphones moving around stage into different positions and the cross signaling of their outputs going into each other’s inputs – ie “feedback

In the video below, Dugan explains the problems he encountered working on the live production of Hair, in which there were 16 area mics, 10 mics in the band, 9 hand mics, and one wireless mic – all operated by one person on a manual mixer.

Dugan played around with voltage-controlled amplifiers (VCAs) for several years in the early 1970s to solve the problem of spontaneous feedback and noise buildup, devising a system that used a distant reference microphone which accepted the signals from stage microphones. The output of each microphone was automatically adjusted depending on the input received by the reference microphone in real time via the reference mic. This enabled the system as a whole to avoid unwanted feedback while also balancing microphone levels. As he explains in Sound and Video Contractor, “I was messing around with logarithmic level detection, seeing what would happen if I used the sum of all the inputs as a reference. That’s when I accidentally came upon the system. It was really discovered, not invented.” he says. “I didn’t really know what I had, just that it worked like gangbusters.”(Sound and Video Contractor 2006).

His two main mixing systems, the Dan Dugan Speech System and the Dan Dugan Music System are demonstrated here in split-screen during a David Letterman show

On his website, Dugan explains that his products, the Model D, E, M, N, Dugan-MY16 and the Dugan-VN16 are “accessories” to sound mixing consoles, not mixers in themselves. The products are patched into the insert points of the send and return loops of each individual channel on an existing console. Thus, mics do not need to cued and faders can be left alone unless tweaked when used. As Dugan writes, “This frees the operator from being chained to the faders.”

It is clear that live sound design would not be the same without Dugan’s pioneering efforts. Dugan remains active operating Dan Dugan Sound Design in San Francisco, CA. You can check out his products and more at He has an extensive list of products all based on and stemming from his original designs and creations. His products have notably been used by CBS Late Night with David LettermanOprahHollywood Squares, WABC in New York, WETA in DC, WVIZ in Cleveland, U.S. presidential debates, ESPN, NBC, CNBK, CBS, Fox Sports, MLB Network and more.

Charlie Richmond

A contemporary of Dugan’s, Charlie Richmond was born January 5, 1950, and is an American inventor who came onto the scene in the 1970s and like Dugan, began creating solutions to solve the problems faced by live theater. In 1975, he addressed the need for a mixing console that would take 100 inputs, and wrote “A Practical Theatrical Sound Console” for the Audio Engineering Society (AES). In it, Richmond describes a unit which elegantly and economically allows one operator to control 100 controls at once without the need of a computerized assistance. The paper is in the AES online library which can be viewed by members or purchased.

Richmond launched Richmond Sound Design in 1972 and was the first to produce and market two new off-the-shelf products for theater mixing, a sound design console named the Model 816 in 1973 and a computerized sound design control system in 1985 – Command/Cue. In addition, he invented the “Automatic Crossfading Device,” trademarked “Auto-Pan” in 1975. According to the Richmond Sound Design website, the Model 816 was “matrix-equipped and included our patented AUTO-PAN™ programmable crossfaders” and revolutionary at the time. Richmond’s company went on to create the Command/Cue computerized audio control system used in multiple theater performances, theme park shows internationally and in Las Vegas. In 1991, with Stage Manager show control software they pioneered the use of MIDI to manage multiple media controllers including sound, lighting, lasers, etc which became an industry standard for all types of live shows from Broadway to cruise ships. Since then, Richmond Sound Design has contributed significant sound software and hardware that have greatly expanded the possibilities of live sound design including: the MIDIShowCD in 1994 which provided multichannel sources at the fraction of the cost, the AudioBox Theatre Sound Design Control system, the ShowMan software and the ShowMan Server Virtual Sound System which brought compatibility for all of its products to an industry standard.

Richmond and Mushroom Studios

Richmond also brought his success with live mixing to studio music mixing by purchasing Mushroom Studios in Vancouver, British Columbia, Canada in 1980. Richmond hosted concert musicians to score many feature films including the film score album of Top Gun. Skinny Puppy, Tom Cochrane, Fear Factory, and Sarah
McLachlan were some of the notable acts that recorded there. Richmond sold the studio in 2006. Clearly, talent with sound bleeds over from sound design into music mixing and sound leaders like Richmond can easily traverse both realms.

Richmond’s Writings

What might be most striking in Richmond’s relation to sound is his gift with written language and his visionary nature. Software such as Garage Band which comes free with Mac products today, and professional software such as Logic Pro and ProTools were obviously only a distant dream of sound designers 30 years ago. In Theatre Design & Technology Magazine, 1988, Richmond contributed a piece entitled “A Sound Future” and in it he predicts the invention of the Digital Audio Workstation (DAW) that inundates the sound world today. As he writes:

Sound designers have been waiting for a long time for a system which allows us to create soundscapes easily, almost intuitively: a system which would perform as a transparent extension of our desires, a tool which requires no interpretation between wish and result. – Charlie Richmond 1988

In 1988, he also predicts the creation of the graphically oriented interfaces that we use today, buttons, etc:

Just point at the picture of the deck and click the mouse button and the (graphically represented) reels will start turning, click again and they will stop. Great, but …what about all the different types of loudspeakers? All of a sudden, I start seeing a lot of work for our software people and a delivery date of some time in the 1990’s for a customized system.Charlie Richmond 1988

Again, visionary. Richmond goes further to suggest how digital graphics could be used to control the parameters of software and it is reminiscent of the many DAWs we see today:

Maybe we should be able to display a big picture of the loudspeaker representing the output in which we want to increase the volume. We could represent the overall volume of the loudspeaker by changing the overall size (volume!) of the graphic representation. Charlie Richmond 1988

Dugan and Richmond have both significantly contributed to the hardware and hence the software that enables sound designers today, both live and in the studio, to create in ways never before possible and perhaps never possible without them. I find it interesting how it was the demands and problems specific to live theatre that propelled Dugan and Richmond to invent new solutions to audio problems that live bands and studio recordists meet, or world have met, without them.

Hans Jenny and The Sound Matrix

Cymatics and the Sound Matrix

Humans have long considered sound and music as mystical and magical, whether worshipped by the ancients and embedded in political and culture in ancient China, regarded as a portal to the infinite by Buddhists chanting OM, or modern day musicians and sound designers revelling in and revering their own sound creations. Sound inspires poets and sculptures across the world, leaders, rebels, teachers and students, the “everyday man” both old and young alike. Sound plays major roles in human life, from the first cry of the newborn baby to the final breath and “death rattle” of those passing. For most of us, sound encompasses our entire lives and every breathing moment. At times it is to be rejoiced, other times to be escaped (has anyone else ever asked the room, “Can everyone just be quiet for a minute please I can’t think!). It is argued that pure silence only exists in “space”. Truly, sonic vibrations are as prevalent as particles of light, moving atoms back and forth within this physical plane. There is a concept that unveils this, a belief in a natural structure that exists beyond the human world and is and embedded in the physical structure of the universe itself: the sound matrix.

Hans Jenny: Pioneer in Cymatics

The belief in a sound matrix is the idea that a pre-created and predetermined sound configuration exists innately in the universe, one that can be exposed and studied. Several scholar/scientists have contributed to this field: now known as “cymatics,” a term applied by researcher Hans Jenny (1904-1972). Essentially, he explored a myriad of different distinct patterns created when particles are placed on a plate and vibrated at different frequencies. In other words, cymatics is the study of wave phenomena that created repeatable physical patterns from the frequency sound vibration of particles. His bookCymatics: A Study of Wave Phenomenon and Vibration  is the defining work to be discussed further on in this post.

The inspiration for the exploration into cymatics is steeped in “anthroposophy,” a philosophy founded by Rudolf Steiner (1861-1925), which states that human beings can intellectually access and uncover elements of an existing spiritual plane. In fact, Jenny’s own book is “Dedicated to the memory and research of Rudolf Steiner.” Anthroposophists believe that the witness of the spiritual world and its demonstration through experiments in fields such as cymatics will stand the test of rational verification. This foray into sound study is an example of the founding principle of anthroposophy and mimics the methods of the natural sciences in their practices of evidence-based research. Before Jenny, however, there are a few other individuals that paved the way for this exploration into the unseen structures embedded and surrounding us in our universe.

The beginnings of cymatics

Ideas of inherent vibrational patterns in the natural world began centuries ago, with Galileo Galilei often quoted as an early witness to the phenomena from his writings of 1632 in his “Dialogue Concerning the Two Chief World Systems.” He explains his experiences when scraping a plate of brass with a chisel, attempting to clean it. Galileo noticed both a high whistling sound and the production of parallel streaks of brass particles that only occurred in tandem with the sound. Fifty years later, scientist and musician Robert Hooke, in 1680, noticed nodal patterns created with vibrating glass. Using a violin bow on a flour covered glass plate, he produced repeated patterns. One would think today, imaging back, that both of these experimenters must have experienced something mystical. They discovered, or uncovered, a structure within the physical world not yet noted by humankind; a matrix that predates history, clearly put in place by a non-human force. No wonder their testimony has withstood the test of time.


One hundred years after Hooke’s observations, one Ernst Florence Friedrich Chladni (1756-1827) published “Entdeckungen über die Theorie des Klanges” translated to English as “Discoveries in the Theory of Sound.” Chladni was inspecting the properties of “Lichtenberg figures.” German physicist Georg Christoph Lichtenberg discovered these radial patterns in in 1777 when placing powdered material on a high-voltage plate. Chladni had the intriguing impetus to run a violin bow along a metal plate holding powder (some say sand), which created vibrations and thus arranged the particles into patterns, creating visibility to the vibrations.  It’s a complex phenomenon due to wave behavior with the particles being moved from the “antinode” to the “nodal” lines, but suffice it to day – really cool patterns emerged. “Hmmm … wow, what are these fantastic shapes appearing from sound? From whence do they come?” Chladni may have asked.


A good while later, Hans Jenny whistled his own experimental tune of the 1960s and worked diligently for over a decade to create and study patterns created by vibration in the exact same vein as his predecessors. With the aid of years of technology, his vibrating method was superior to those before him in its accuracy. He used crystal oscillators and tone generators to control the frequency and amplitude of his signals as opposed to the anvil of Galileo and the bow of Chladni. Jenny connected these devices to metal plates and his methods were repeatable, a necessary condition in scientific research. Below is an example of the intricate patterns that Jenny uncovered through his work. This, in particular, is the latticework in liquid, seen in video below

Jenny’s Work and Theory

Jenny published Kymatik (translated Cymatics) in 1967 after, as mentioned, more than 10 years of intense study. When reading through his work, found at through a google search of “hans jenny cymatics pdf,” his adherence to anthroposophy is obvious as he continually attempts to connect the dots between his work and other periodic systems throughout the physical world: “Whenever we look in Nature, animate or inanimate, we see widespread evidence of periodic systems. These systems show a continuously repeated change from one set of conditions to another, opposite set”(Jenny, 17) He mentions human circulation and respiration, the cycles found within the vegetable and animal kingdoms and goes into chemistry as he sets up the argument for cymatics as a structure of the universe predating humankind: that the organization of the sound matrix is prime and found throughout all matter, and recognized throughout his work.


A colleague of his, Jeff Volk, sums up the most poignant of Jenny’s ideas succinctly in his introduction. He writes: that “the principle underlying Cymatics, that of periodicity, is so ubiquitous in nature (and in Nature), that it is found in all manner of phenomena.” Volk further reflects on how Jenny’s discoveries “mirrored biological forms and natural processes, as well as flowers, mandalas and intricate geometric designs … these experiments seemed to reveal the hidden nature of creation, to lay bare the very principle through which matter coalesces into form.” Volk The most striking of Volk’s points is that Jenny’s shapes were the result of “audible vibration.” In other words, cymatics allows us to see sound.

By carefully controlling the frequencies he generated and the area size of the metal plates, Jenny could compare various substances such as sand, fluids, and powders at different frequencies and in different areas. The vibrations had a large range which resulted in a large array of various geometric shapes. From these he noted three fundamental principles of vibration and wave motion. One pole exhibits patterns and figures which is visible. The other pole demonstrates kinetic processes (plate vibrations) which is audible. Third, the entire process is periodic, which Jenny terms “essential periodicity.” The concept of essential periodicity is significant in understanding Jenny’s mission: “essential” refers to patterns that are of the essence of the physical world, and periodicity clearly that periodic cycles are also embedded in the physical plane.

Jenny explores a wide array of different frequencies on different media resulting in a striking variety of visible patterns: square metal plates of various sizes, triangular plates with crystals attached to their underside, The images in this video begin at 2:07

The moments above and others through the video are reminiscent of other living and non-living beings and figures found in nature, clearly. I will end this post with Jenny’s own words which I’ve transcribed from the video above and shed further light and is purpose and vision on the primacy of sound:

You will see many things that answer many questions. You will see living forms, living amoeba, almost animal-like creatures, you will see continents being formed, the earth itself coming into existence, explosions, eruptions, atomic explosions and bombs, you can see all this and watch it before your eyes. But everything owes its existence solely and completely to sound. Sound is a factor which holds it together. Sound is the basis of form and shape. In the beginning was the word and the word was God. We are told this is how the world began and how creation took shape.~ Hans Jenny

Music of the Minor Modes

The prior post concerned the three major modes which are designated by their major 5ths. The minor modes are similarly designated by their minor 5ths. Each has a unique history and flavor, but they share the familiar minor darkness of emotion in common. From the bittersweetness of the Dorian, the tense power of the Phrygian, to the floating lunacy of the Locrian, they all hold a distinct place as one of our seven modern modes.

Mode II: Dorian

The first minor mode is the second of seven modes (three major and 4 minor) – named Dorian. In C major the sequence of notes begins on D: D, E, F, G, A, B, C, D. It’s intervals are very similar to the natural minor scale (known as the Aeolian), but it has a raised 6th note. This raised 6th is the peculiarity of the Dorian mode that gives it a special feel, wistful but not tragic, due to the brighter interval from the raised 6th.  The sequence of steps is W, H, W, W, W, H, W (with W being whole-step and H being half-step) laid out in a symmetrical manner with the three wholetones in the middle bordered by halftones and ending on each with a whole tone.

The Dorian scale derives its name from the Dorian Greeks, who are mentioned in Homer’s Odyssey as living on the island of Crete. It was a scale during the Greek period and one of the church modes of the Middle Ages, as well as existing in a current modern form. Russian composer Mily Balakirev (1837-1910) gave prominence to the Dorian mode when studying the structure of folk songs and dubbed the mode the “Russian minor.” Tracks of recent era seem to have a dark but hopeful sense to them, sad but not crushingly desolate. To me, at least, these songs share a common sound and I suppose it’s because they all employ the Dorian mode: “Scarborough Fair” by Simon and Garfunkel, “Eleanor Rigby” by the Beatles, “Purple Haze” by Jimi Hendrix, “Evil Ways” by Santana, and “Who Will Save Your Soul” by Jewel. If your in the mood to compose something in this vein, play around with the Dorian mode.

Mode III: Phrygian

Phrygian, the second minor mode, is the third of the seven modes. In C major the sequence of the notes begins on E: E, F, G, A, B, C, D, E. Like the Dorian mode, the Phrygian is nearly identical to the Aeolian, but with a flat 2nd, giving the interval a dark and tense feel. This note sequence is especially tasty for metal tracks as with “Wherever I May Roam” by Metallica. This flat 2nd gives the Phrygian it’s unique characteristics, unexpected by most modern listeners accustomed to the normal whole step from the first to the second notes in both the normal major and minor scales (Ionian and Aeolian), giving an impending negative mood.

Interestingly, it has the same notes as F minor, a common key in horror scores. The sequence of steps is H, W, W, W, H, W, W, and its sequence gives mysterious sounding mode and also coined the “Gypsy mode.” The notes constitute an E minor chord OR an E major, which with a C major scale played on top is reminiscent of “Spanish Music” as guitarist John Heussenstamm demonstrates:

The Phrygian mode is named after the ancient kingdom of Phrygia in Greece. Its music contributed to Greek musical traditions through Greek colonies and the mode is associated with combat and war. In fact, according to scholars the ethnic name Phrygian describes the wild and passionate people of the mountainous regions in Anatolia. It would make sense then, that the music derived from this mode does not fit neatly into the traditionally common Western Ionic/Aeolian box, being of the strange and the wild. Also, it’s not surprising that it lends itself to heavy metal with it’s wildness and power.

Mode VI: Aeolian

The Aeolian is the third minor mode, the sixth of the seven modes. Its series of pitches corresponds to the natural minor scale in Western music. In 1547, music scholar Henricus Glareanus first named and described the Aeolian in his treatise on music Dodecachordon. He added to the eight church modes that had dominated for 600 years to include newer major and minor modes and the Aeolian was one of the four (the others being Hypoaeolian, Ionian, and the Hypionian). The Aeolian used A as its tonic and matches the current minor of C major: A, B, C, D, E, F, G, A with flats on the 3rd, 6th, and 7th. As with the other modes, Aeolian was named after an ancient Greek ethnicity – the inhabitants of Aeolis on the Aeolian Islands.

The sound and feel of the Aeolian mode, ie the minor scale, is commonly known even among non-musicians. It quite simply is the opposite of the major scale. While the major scale, the Ionian, is bright, happy, cherry and optimistic, the Aeolian is dark, sad, foreboding, and heavy. Often songwriters will move from a major scale to its minor counterpart during a transition or bridge. Again, it is striking that simply by rearranging the exact same notes from Ionian to Aeolian one can create an incredibly different sound and feel. REM’s “Losing My Religion” is in Aeolian, the natural minor:

Mode VII: Locrian

The fourth minor mode is the Locrian, the final of the entire seven modes. The triad based on its tonic is a diminished chord and is dissonant from B to F and termed a “tritone”  – an interval of three whole tones. B is the tonic with the intervals H, W, W, H, W, W, W and the notes B, C, D, E, F, G, A, B. While Glareanus in 1547 happily added Aeolian to the canon of acceptable modes, the Locrian was left out, as it attempts to resolve on the B and creates the dissonant tritone. The mode is named after the Greek regions of Locris. Yet while the name Locrian harkens back to this era, it is rarely used and finding examples of its use difficult. 

The dissonant tritone was not accepted into music for centuries as it fell under the label “diabolus in musica,” meaning the devil in the music. The tritone, and hence the Locrian, was forbidden until the Baroque era when it was used within limit. The sound of the Locrian can be sinister and unsettling as it is used over half-diminished chords and has the same pitches as B-flat Aeolian and D-flat Ionian. It uses notes and combinations of notes not in the norm of western music and tends to be avoided unless perhaps one wants something very horrific and disturbing. Some musicians, heavy metal of course, do use the mode as a scale to build riffs such as in “Sandman” by Metallica as noted by Christopher Smith on “What are some of pieces that use the Locrian mode” on

Smith goes on to explain that, as stated, the Locrian mode doesn’t sit well with Western ears, but that it is used frequently in the music of South Asia, the Middle East, and North Africa. He mentions that some Egyptian and Persian melodies in the folk tradition adhere to the Locrian mode. He writes further that three techniques have been used to solve the resolution problem with the chord cadence in the Locrian. 1. Just end on an octave note, not a final chord. 2. Use a minor chord to end instead of the diminished, but only in the final chord. 3. End on a flat 6th chord which suits as an ending yet leaves the piece feeling not quite resolved. In Western music though, it can be used to rock as with this demo of “In Your Words” by Lamb of God.

Because of this open-ended and unappealing feel of the Locrian mode, it has been called a “theoretical mode.” In other words, it exists in theory just as fine and dandy as the other modes, but in practice it is not widely used. It comes down to theory. In this case since the Locrian does not have a perfect 5th it sounds basically terrible and is unable to resolve if one intends to adhere to it perfectly, which essentially no one does. The mode is reminiscent of the Lydian major mode in that it floats rather than grounds itself. And, perfectly, Bjork, who uses the Lydian mode a bit in “Possibly Maybe,” also uses the Locrian in “Army of Me” briefly in the bassline. This makes sense of course as Bjork is the quintessential experimenter.

What is striking about these modes and their unique characters and the emotions that they elicit is this: they point to a pre-existing structure and pull us toward obeying that structure. A perfect fifth is a necessity, at least in Western music, or it sounds dissonant. Why? As with Hans Jenny’s work discussed in another blog post here on Cymatics, there is evidence of pre-existing order that humans are tapping into. To me, it’s the same question I ask regarding math. Did we invent math or did we discover it? Did we invent music or did we discover it?
