Mark Smythe, the New Zealand-born composer and educator based in Los Angeles, died at age 53 after suffering a cardiac emergency on a popular hiking trail.
The incident occurred on Saturday, May 9, 2026, along the Mount Wilson trail near Sierra Madre in California. Responders arrived quickly but could not save him. The Los Angeles County Medical Examiner ruled the cause of death as atherosclerotic cardiovascular disease.
Smythe chaired the Composing for Visual Media program at the Los Angeles College of Music. He used that position to train the next generation of composers working in film, television, and other visual formats. Throughout his career he also took on executive responsibilities in addition to his creative output as a composer.
Composer Bear McCreary, known for his work in television scoring, voiced his dismay upon learning of the death. "I'm shaken to hear of the shocking and untimely passing of Mark Smythe, a prominent figure in the Los Angeles film scoring community, particularly with the Society of Composers and Lyricists, and a talented composer in his own right," McCreary said.
Industry observers noted that Smythe occupied a distinctive place by combining hands-on composing work with administrative and teaching duties. His background from New Zealand gave him a fresh viewpoint in the Los Angeles scene. Students and peers alike benefited from his expertise and guidance over the years.
The Variety and Los Angeles Times reports highlighted how his passing leaves a gap in both the creative and academic sides of the scoring world. Hiking in the Sierra Madre area is common among residents seeking escape from the city, yet the trails can prove strenuous. Smythe's death underscores the unpredictable nature of such health events.
Those who knew him describe a professional who balanced multiple roles with apparent ease. His legacy will likely continue through the composers he mentored and the music he created during his time in the industry. The film scoring community in Los Angeles will remember his contributions for some time to come. Smythe leaves behind a rich body of work and many inspired students who carry on his teachings in film scoring techniques and professional development.
