The use of information and communication technologies (ICT) in schools is now commonplace and, for many, an unquestionable part of everyday teaching and learning. But detailed studies of the use of ICT in classroom-based music education are rare. This article explores how pupils aged between 11 and 16 used ICT to create and perform music in new ways. Working as a teacher-researcher, the author used the methodologies of action research and case study to investigate how pupils engage with and organise sounds with ICT.
