Kirin Nielsen
Copy Editor - In Perfect Harmony
Two threads of excellence and pursuit in Kirin Nielsen’s professional work are clear: words and music. Whether one or the other or both are prominent, elements of the two inform the expertise she offers and the intellectual and creative approaches she brings to solutions. As an editor, copy editor, writer, teacher, and writing coach, Dr. Nielsen has a keen eye and ear for clarity, accuracy, and tone. She is a patient, supportive editor who maintains high standards for the author and herself in many contexts. Her persistence and curiosity combine to make her an able researcher of ideas, information, and reliable sources as an author, editor, and fact-checker.
Most recently, Nielsen was an associate editor at GIA Publications, where she edited more than fifty books on a variety of topics in music education, resources for professional choral musicians, resources for church musicians, and textbooks for undergraduate and graduate-level students of music education. In addition, she was a proofreader of musical scores as they went through the engraving process.
Nielsen’s exceptional training as a musician, both as practitioner and teacher, gives her the ability to consider many ideas and circumstances at the same time. She has been a professor of music at the college level, contributing the most when in the context of teaching and mentoring individuals and small ensembles. Also, her work as a conductor required her creativity, deep knowledge of her subject, organizational skill, ability to work with a broad variety of individuals and groups, and talent for building ensembles whose individuals respected one another.
Dr. Nielsen earned her Bachelor of Arts degree in English literature from Cornell University, where she also pursued her interests in art history and studio art. She completed her Master of Music degree with a concentration in choral conducting at the renowned Westminster Choir College. Finishing at the top of the class, she was made a member of the national music honorary society, Pi Kappa Lambda. Finally, Nielsen earned the Doctor of Musical Arts degree from the University of Illinois at Urbana-Champaign, and with it, membership in Phi Kappa Phi national graduate honor society. Her most notable accomplishment was the national Herford Prize for Excellence in Research, which is presented by the American Choral Directors Association to at most one doctoral dissertation per year.
Kirin Nielsen’s further interests include art history and museums, travel, international cultures, languages, politics, and her spoiled cat.
