SA music teachers not in tune with changes

Music teachers in South Australia will down their instruments and stop work on Monday to protest against changes to public school music lessons.

The changes mean teachers from the state's Instrumental Music Service will be based at 20 locations across SA rather than working as a single unit.

The Australian Education Union's SA President Howard Spreadbury says teachers are concerned the shift will prevent them from working collaboratively and will dilute the specialisation of the service.
