This study investigates how a class of university music students who engaged in a "lived" experience of informal learning adopted methods and strategies to complete a self-learning "aural copying" performance assignment in a musicianship class in Hong Kong. Data were collected from observations of the performances and the students' written reflections. The findings showed that they used the methods of intensive listening, using technology, and collaborative learning, as well as the strategies of putting their knowledge of music theory into practice, substitution of instruments, and learning a new instrument in order to emulate the sounds of various instruments. They found this an interesting task that gave them opportunities to improve their musicianship, and they became more sensitive to different voice parts.
