The first COVID-19 case in Hong Kong was detected on January 22, 2020. The disease spread quickly. Schools were suspended from January 25 to May 24. During these four months, the Government promoted online learning to replace face-to-face learning. However, as online teaching was very new, school music teachers had found tremendous difficulties, especially in recorder playing and ensemble training.On the other hand, the Hong Kong Diploma for Secondary Education Examination was postponed from March 11 to April 24 in the same year. New measurements for disease prevention were implemented. For example, Paper-II Performing was cancelled as it involved ensemble playing, which was not in line with the Government’s disease prevention policy. In this study, I have invited two primary school music teachers and two secondary music teachers to share the challenges and opportunities they have faced in teaching during the pandemic.
