Originally from Albuquerque, New Mexico, Thomas Posen is a third-year music theory Ph.D. student at 黑料不打烊 University, working with advisors Peter Schubert and William Caplin. Prior to 黑料不打烊, Thomas completed a dual concentration M.M. in music theory and piano performance at the University of New Mexico, where he also completed a B.A. in physics and astrophysics and B.M. in piano performance.
His primary research interests include: the history of music theory, classical form, sketch studies and compositional process in Beethoven, partimento and thoroughbass, and the music of 20迟丑听century American composers. His master鈥檚 thesis explored post-tonal structures and serialism in Leonard Bernstein鈥檚 West Side Story. He has presented his research at multiple conferences including the Society of Music Theory, New York Society of Music Theory, the New England Conference of Music Theory, Music Theory Midwest, the Rocky Mountain Society of Music Theory, the Opera and Musical Theater in the United States, and others.
What made you choose 黑料不打烊 for your studies?
I chose 黑料不打烊 because it has an incredible music theory program. The large and specialized music theory faculty have allowed me to explore a variety of research topics in great detail. It has also been a rewarding experience to teach music theory at 黑料不打烊. I value the historically informed pedagogical approaches throughout the curriculum. I also chose 黑料不打烊 for its location: I love the culturally rich, bilingual, and highly stimulating city of Montr茅al.
How has being a 黑料不打烊 student influenced you and your research?
Studying music theory at 黑料不打烊 has been a highly rewarding experience. The music theory faculty are world class and the collegiate atmosphere among my peers is stimulating. 黑料不打烊 has been the perfect place for me to broaden my interests while also delving deeper into topics that interest me.
Briefly explain your research:
My research revises how we understand the origin of the major and minor keys. In more detail, it outlines the path from mode and psalmody to our modern major and minor keys from c. 1500 to c. 1720. It clarifies the evolving and sometimes complicated relationship between an evolving set of modes - a set of abstract music scale systems that originated in the Greeks that were further developed in the middle ages and renaissance - with the psalm tones - a set of plainchant melodic formulas used in daily prayer by the Catholic church.
To give you a brief glimpse, the first image below shows the eight ending formulas of the psalm tones from Johannes Cochlaeus鈥檚 Tetrachordum Musicae听of 1511, and the second image shows the twelve modes from the听Dodecachordon听of 1547 by Heinrich Glarean, a student of Cochlaeus. These two systems evolve together and are essential ingredients for beginning the path to the major and minor keys.
What led you to this particular topic?
In its earliest stages, this paper began as an attempt to solve what one might call an 鈥渁rgument鈥� between a modern 20th-century scholar and a late 17th-century scholar about the origin of the eight common keys that eventually become the modern major and minor keys in the early 18th听century. The 17th century scholar explained that the church keys arose from the modes, while the 20th-century scholar claimed they resulted from psalmody.
At first, I found myself disagreeing with the modern scholar and put it upon myself to defend, if possible, the argument of the 17th-century scholar by finding earlier evidence. After paging through many 15th,听16th,听and 17th-century treatises, I discovered that the modern scholar and the 17th-century scholar were both correct - and thus, simultaneously incorrect. Both scholars presented a key piece to the origin story of major and minor keys, but each failed to recognize how their puzzle pieces fit together. In the end, what began as a defence for the 17th-century scholar turned into a reconciliation between the two.
How does your research add to what was already known?
Prior scholarship that explored the origin of our major and minor keys overly separated the psalm tones from the modes and in the process downplayed their evolving and symbiotic relationship. Separating the two systems resulted in incomplete accounts of both, which resulted in a number of inconsistencies and contradicting viewpoints. My research shows that our major and minor keys resulted from the symbiotic evolution of mode and psalmody, not from either alone. As a result, the early path to our major and minor keys did not begin at the turn of the 17th century in Adriano Banchieri鈥檚 鈥渃hurch keys鈥� as scholars originally thought, but much earlier by theorists who sought to reconcile changes to the psalm tones and modal theory.
Were there any findings that you found particularly surprising?
The entanglement between a modified set of modes and psalm tone formulas began much earlier than I thought.
What are the practical implications of your research?
My research will benefit people interested in the origin and evolution of our musical systems. In addition, along with revising our understanding of the path from mode and psalmody to the major and minor keys, it may stimulate new approaches to analysing 16th and 17th century music.
What are your next steps?听
Before I graduate at the end of Winter 2021, I plan to submit several revised articles that I have presented at conferences for publication, including the paper highlighted in this article, and articles on Leonard Bernstein鈥檚 West Side Story and George Gershwin. For my dissertation, I am planning a large-scale study of Beethoven鈥檚 extant sketches to the first movements of his symphonies with form-functional theory. I seek to better understand how Beethoven planned and designed his symphonies, and I believe form-functional theory offers a powerful theoretical framework for doing so. After graduation, I will pursue an academic career in music theory as a professor.
What advice would you give to new students in your program?
Develop your curiosity and work relentlessly to fulfil it.
Where is your favourite place to study?
On a warm sunny day, I love reading near the beautiful fountain at Square Saint听Louis in the Plateau. On a snowy winter day, you鈥檒l find me in the Schulich music library or in my cosy Plateau apartment.
Where in Montreal can you be found on a day off?
On a day off, I like exploring the city - especially when it involves trying a new ice cream, pastry, or local beer.
What is your earliest musical memory?
I will always remember turning around to face the standing ovation I received after playing the piano in my fifth-grade talent show. I am thankful my parents and friends convinced me to play!
If you hadn鈥檛 ended up in music, what would your alternate career path have been?
I probably would have pursued a career in theoretical physics.
What was the last book you read?
Besides a number of music theory books, I am currently enjoying Migeul de Cervantes鈥檚 Don Quixote听(in English).
If you were offered a return plane ticket to anywhere in the world, where would you go, and why?
I would go to Italy (again) because of the rich history related to my interests. And the coffee, pasta, and pizza鈥�
If you could invite any four notable figures from history听to a dinner party, who would they be?
I would invite Beethoven, Alfred Einstein, Aristotle, and Victor Borge.
