The COVID-19 pandemic forced educators across the world to quickly move their instruction to a virtual or hybrid environment. Teachers experienced a wide variety of adverse situations stemming from teaching online, and their experiences depended upon their technology training as well as their access to technology resources. The problem addressed in this qualitative multiple case study concerned the struggles music teachers experienced with technology training and in using technology during the COVID-19 pandemic, and these experiences impacted their ability to effectively teach in a hybrid or virtual environment. The purpose of the study was to obtain and examine information from middle school music and non-music teachers about technology training during their undergraduate teacher education programs and professional development and how their technology training affected their teaching experiences in a hybrid or virtual environment and in continuing to teach with technology. Participants in this study were 22 middle school teachers, divided into two cases of music teachers and non-music teachers, and participants completed 60-minute individual interviews via web meeting. Five participants also volunteered to participate in a focus group session via web meeting. The data from both the individual interviews and the focus group session were transcribed, coded, and categorized into themes that helped answer the study's research questions. A cross-case analysis was also conducted to determine if other themes emerged between the two cases. From the three research questions, several themes emerged. The results of the study indicated that music teachers had experienced some technology training and had access to some technology resources, but much of the technology training and resources were not adequate or useful to teaching music with technology. Recommendations for practice include revising music teachers' technology training during their teacher preparation programs and professional development sessions. Future research is recommended to determine the extent of technology training and adequate technology resources required for music teachers to be able to teach with technology effectively.
