Students are encouraged to record at least one piece per term (usually two). A recording is made at an 'almost finished' stage to assist in self-correcting the piece. Then a further recording is made to help critical listening and assessment details. A final recording is made of all pieces being prepared for recitals.
At the end of the year, recordings are emailed home as an aural snapshot of the year's work. Think 'school photos', 'art portfolio' and similar.
