Arbor Sketches

1967 / edited 2023 . . . piano or harp (6:40)

In 1967 I was already earnestly composing for piano, trombone (my own instrument), even for orchestra. Living beside the Shiawassee River’s glacial-moraine beginnings in rural Livingston County Michigan, my best pastime was hiking along the creek’s forested banks. I was already going to Ann Arbor for trombone lessons and Youth Symphony rehearsals. In fall 1967, after my 18th birthday, I moved to Ann Arbor and enrolled at the University of Michigan. Though not yet a music major, I began playing bass trombone in the university orchestras. For 8 years, Ann Arbor with beautiful Huron River running through it was my forested Michigan home.

“Mystic Breeze” and “Light” were my 12th and 18th completed TC compositions. “Riverbank” is from a 1967 sketch of an “interlude” for trombone and piano. They make a nice set of three, revealing that before formal study my compositional explorations were already discovering more exotic harmonies and rhapsodic forms resembling Debussy’s Impressionism and even the post-tonal possibilities of 12-tone rows.

Looking back 55 years later, it turns out that once I began studying composition at Michigan, my first teacher, American-in-Paris composer Eugene Kurtz, immersed me in studying the music of Ravel and Debussy. The next teacher, George Balch Wilson, plunged me into the newer language of atonality and the radical explorations of the Avant Garde.

Hawking’s Time

2023 . . . sound sculpture . . . 5 minutes

Stephen Hawking, the great theoretical physicist and cosmologist, is famous for solving in 1974 the mind-boggling mathematics of black holes and what became known as their Hawking Radiation. He also wrote a fascinating book, A Brief History of Time. Now, after Hawking’s death, his last collaborator, Thomas Hertog, has published On the Origins of Time explaining Hawking’s theory of how Time itself began at the Hot Big Bang birth of the universe. The idea, in grossly simplified geometry, is that Space and Time were united as one primordial sphere that dramatically split apart at the Big Bang’s initial hyperinflation into expanding Space and progressing Time. Before that moment, there was no time, no before.

The musical challenge: how to express utter timelessness before the explosion; and how to build a sound space that sits still then explodes. You’ll hear an initial sound space of just one pitch, G, which at first quivers in color but without perceivable rhythm. While standing still, the sound space expands by octaves and eventually explodes with a fuller spectrum of chromatic pitch color. The history of Time compressed into a brief five minutes!

Viennese Sketches

Twelve Miniatures in Twelve Tones

2023 . . . chamber orch: Fl, Ob, Clar, Bsn, Strings . . . 12 minutes

I have long admired and been influenced by the music of early 20th-century Austrian composer Anton Webern. Known historically as a member of the Second Viennese School with Alban Berg and mentor Arnold Schoenberg, the three were pioneers of so-called atonal music and 12-tone-row serial harmonic organization. I find the term “atonal” misleading and negative, as their 12-tone processes achieved new “12-tone tonalities” — not simply a rejection of traditional tonal harmony but also striving to create new and more complex tonalities.

What I admire about Webern’s mostly-quiet instrumental miniatures (his Symphonie Op. 21 has only two sparsely-scored movements) is the delicate, crystalline quality of his pitch constellations; and their gently lyric, precious setting into transparent textures, pearl-strings of delicate sound colors (called Klangfarbenmelodie).

Webern’s mentor, Schoenberg, as a Jew was compelled to emigrate to the U.S. in 1933 before it was too late. Webern, not Jewish, stayed in Vienna and survived World War II, only to be fatally shot by a U.S. Army soldier during the Allied occupation of Austria.

Miniatures I through IV are adapted from Webern Elegy and V through XII from MapLab7For Little Arnold. Viennese Sketches does not portray the historical European city but rather explores various musical textures and tonalities using the 12-tone serial techniques of the so-called Second Viennese School of composers associated with Schoenberg. While their music using these techniques was unfortunately dubbed “atonality,” my uses focus on creating constellations and counterpoint that is complex but much less dissonant and more sonorous, my sense of a new tonality.

While the chamber orchestra work is organized in the traditional symphonic four movements, each miniature is excerpted below to show changing pace and textures.

Passing Storm

Animated Landscape No. 4

2022 . . . sound painting (4:30)

In 1973, I composed my second orchestra piece as a graduate student at the University of Michigan. The title was inspired by John Cage’s famous Imaginary Landscapes No. 4, which we performed as I was an ensemble member of Contemporary Directions. The idea of animating an otherwise static sound mass, devoid of progressive harmony, was a quintessential feature of what I came to think of as the Midwestern Style of 1960s and 1970s large ensemble music. Successful models included prize winning pieces such as (my teacher) Leslie Bassett’s Variations for Orchestra (1966), Donald Erb’s The Seventh Trumpet (1969), and Joseph Schwantner’s …and the mountains rising nowhere (1977) and Aftertones of Infinity (1979).

So many great American landscape artists of the 19th century painted fascinating panoramic scenes. One of my favorites, who captured the grandeur of Western, mountainous landscapes, was Albert Bierstadt:

Albert Bierstadt: Passing Storm over the Sierra Nevadas (1870) – San Antonio Museum of Art

You can see stark contrasts in brightness and in sense of motion between the mirror-smooth water and roiling clouds. Even the word “passing” in the title suggests change, a necessary ingredient of an analog musical landscape.

While not trying to actually map the physical composition of any painting, my musical inspiration came from considering this painting’s features of background, foreground, and highlights of strong visual focus. Musical gestures started with distant swelling sonorities, which as they crescendo feel like they are emerging forward toward us. After deciding to name the piece Passing Storm after the Bierstadt, however, I realized I had no storm in the music, just gentle sprinkles. Thus was created a stronger sonic rendering of the sprinkles to provide a more aggressive introduction. The following four minutes overlaps sound masses animated in time, contrasting dark vs. bright sounds, loud vs. soft, and timeless sustained sound vs. busy points of “light.”

Aristotle’s Elements

2022 . . . four sound sculptures for orchestra (15:30)

One feature of my modern-music and composition e-book Mapping the Music Universe is a set of composing experiments called MapLabs. Each provides lab instructions to gather material and make compositional choices, and each provides an example piece built step by step along the path of the lab instructions. The sample pieces for the first four MapLabs fit together here as the metaphorical elements, fire, air, water, and earth, of Aristotle’s concept of the world’s physical matter. My mostly abstract photo images provide a visual background for listening.

Where the amber atoms in the fire gleaming
Mingled their sarabande with the gymnopaedia.

Fresh wind weds the land and water,
Sun warms bright sails and sailor.

Where tiny Otter Creek trickled out onto a more secluded sandy beach
Offering northward a spectacular view of Empire Bluff

The Black Canyon of the Gunnison, named for the ever-present shadows
The narrow canyon’s steep, sheer, tall rock walls cast on the river flowing far below.

Aristotle’s Elements

These images are set in motion by the magic of various Ken Burns effects for a video version on the TClark Art Music YouTube channel.

In another arrangement transcribed for wind ensemble in 2023, the order is changed:

I. Amber Atoms (FIRE) 4:46
II. Fresh Wind (AIR) 3:40
III. Black Canyon (EARTH) 3:12
IV. Otter Creek (WATER) 3:04

Yin Yang

2022 . . . voice and piano (4:10)

A visit to the shores of Michigan’s Leelanau Peninsula inspired me to write a poem:

Peninsula upon peninsula upon grand peninsula,
Lee upon Leelanau upon Lower.
Cove from bay from great lake,
Suttons Bay off Grand Traverse Bay off Lake Michigan

Land curves in myriad shore shapes,
Reaching out to blue water.
Fresh wind weds the land and water,
Sun warms bright sails and sailor.

Setting it as lyrics for an art song made an example for MapLab 2: Sketch a Song. The lab instructions include a step-by-step explanation of the compositional process. (The synthesized audio rendering below is not capable of pronouncing the words.)


These are a distillation of my guiding principles through many years of teaching, serving as an academic leader, and meeting, working with, and understanding many very successful musicians. They don’t really belong on this composer-and-photo-art site. Or do they?

Clark’s Rules for Musician Success

Teaching is not so much imparting knowledge as it is facilitating learning. A teacher is an enabling coach on the sideline; all the on-field action is by the student, the learner. From a veteran coach, here is a simple but effective playbook.

Each rule is a command to action.

Rule 1: SHOW UP.

Music is a team sport, and the team depends on you being there every time.


Don’t just watch and listen — think about what you see and hear.

Rule 3:  DO THE WORK.

Just enough? No, all there is to do.

Rule 4:  JOIN A TEAM.

Commit to the team’s success as your own.

Rule 5:  PLAN AHEAD.

Essential to accomplishing Rules 1 and 3.


It’s a lifelong process of self-development, not a hat you can simply put on.           


Part of Rule 4, this is what it means to be a humane human.

Feel free to quote and pass them on!

The original Clark’s Rules for Musician Success above are basic principles to live by, originally posted in my Texas State School of Music Director’s DIARY on January 16, 2017 . They have worn well, largely drawn from my observation of the common traits of great musicians I’ve had the good fortune to meet or work with.

Clark’s Rules for Good Leadership

As I headed toward the end of my administrative career, I reflected also on the many wonderful leadership mentors I’ve had the honor to work with, especially Dave Shrader. My reflections, incorporating a few of the first 7 rules, were posted in Director’s DIARY on . We start by repeating Rules 5 through 7:


Whatever you endeavor to lead, it’s a lifelong process of self-development.           


Fundamentally, that’s the main thing a leader does.


Enable their good ideas. Trust their skill and commitment. Seek the best in others.


Embrace a true mission. Let the practical goals flow from the mission.

Rule 9:    TAKE RISKS       

Take calculated, reasonable risks worth the payoff. Don’t be afraid of failure. Redefine it as simply not succeeding on the first try.

Rule 3:    DO THE WORK

Not everything can or should be delegated. Be well informed. Know how the systems and teams you lead operate.


Not necessarily quickly. Sometimes with time they solve themselves. Wait while seeking all the information, possibilities you need to consider. For the toughest, brainstorm, think the unthinkable. Engage others in the solution.          


Be considerate but honest. Avoid being unnecessarily judgmental. Transcend stereotypes. Don’t assume you know what’s best for others. Choose the greatest benefit for the greatest number of stakeholders, while being fair to all.


Or just simply give it away. It will come back to you if it’s deserved. Everyone knows anyway, the best accomplishments are team collaborations.

Since 12 is to me an almost magical number, I think I’ll stop . . . for now.

1983 . . . soprano, guitar (7:50 min.) . . . words by Robert Nosow

Robert Nosow was a graduate student in musicology at North Texas when the poem was written. David Lynn Kennedy was a grad student in guitar killed by Denton police in a tragic incident in 1983. Soprano Jing Tam was a doctoral student who also knew Kennedy, one of many NTSU/UNT music students who died during my 28 years there.
