Dr. Randolph Johnson

Chair, Division of Music
Assistant Professor of Music Theory
Low Brass


Dr. Randolph Johnson is dedicated to cultivating musicians' love for music, and to helping them in their pursuit of imaginative music making. He teaches music theory courses that are designed to enrich students' journey as musician-creators, in the image of Jesus, the supreme creator and artist.

In addition to teaching, Dr. Johnson enjoys collaborating with students and faculty on research that uses interdisciplinary methods. His research combines approaches in music theory with techniques from fields such as psychology, linguistics, and statistics. His recent projects have addressed topics in orchestration, mental practice, tempo, facial expression, song lyrics, performance practice, and piano duet music.

Dr. Johnson is also an active trombonist, specializing in bass trombone. While residing in Ohio, he participated on a music ministry team, and also regularly performed classical trombone throughout Ohio; including frequent performances as a substitute with the Columbus Symphony Orchestra. In 2005, he performed at the International Trombone Festival in New Orleans as a finalist in the Donald Yaxley Bass Trombone Solo Competition.

Prior to joining the faculty at Oklahoma Baptist University, Dr. Johnson taught courses in music theory, aural training, counterpoint, and music appreciation at Ohio Wesleyan University and Ohio State University. At OBU, he teaches music theory, aural skills, orchestration, counterpoint, music technology, theory seminar, and low brass private lessons (trombone, tuba, euphonium).

Dr. Johnson lives in Shawnee with his wife, Lia, who teaches English at Grace Christian Academy.
