Music historian Betsy Schwarm spent a dozen years on the air at the vintage KVOD radio, “The Classical Voice of Denver.” She has also taught university-level music appreciation, but is especially known for her user-friendly approach to talking about classical music. She gives pre-performance talks for Opera Colorado, has frequently spoken at the Colorado Symphony, and has written ten books on classical music as part of her Classical Music Insights series. The most recent of these is Classical Music Insights: Between the Wars (2021). More than 200 of her articles are available on Encyclopædia Britannica online. Additionally, she writes for classical performers and organizations throughout the US and abroad, and teaches for the University of Denver Enrichment program, as well as other organizations.
