Our Staff

Dr. Mark Rockwood


Mark began studying music at a young age, starting piano lessons at age five. However, his true love came two years later when he begged his parents to buy him a violin after seeing a violinist in concert. At age seven, he began taking violin lessons and enjoying every minute of it. This brought him all the way to completing a Ph.D. in music theory at the University of Oregon in June 2017. His dissertation focused on sonata form in the chamber music of Antonin Dvořák. Along with his primary area of music theory, he completed a secondary concentration in violin performance at Oregon, studying with Fritz Gearhart.

During his studies at the University of Oregon, Mark taught classes in music theory, aural skills and keyboard skills. In 2014, he developed and taught a class which explored sonata form in orchestral music written in the 19th century. Mark also has extensive private studio teaching experience. He maintains a private violin and piano studio in Eugene. He is also Adjunct Instructor of Violin at Northwest Christian University. He is a registered Suzuki violin teacher, with certification in Books 1-3. As a performer, Mark has worked with many ensembles throughout Oregon, including the Oregon Coast Chamber Orchestra, Cascadia Concert Opera, Corvallis/OSU Symphony, and the Shedd Institute.

Mark holds a Master of Music degree in Violin Performance from the University of Oregon, where he studied with Kathryn Lucktenberg. In addition, he holds a Bachelor of Music degree in Violin Performance from San Jose State University, where he studied privately with Cecily Ward and had extensive chamber music coachings with the members of the Cypress String Quartet.
