Year 2 music: Canon in D - played by Baroque instruments

In Year 2, I think children are ready to start part-singing. I start training them through round singing. I spent a whole month teaching them about rounds and canons; we sang songs and build rounds on board. As a closing to this unit, I chose to show them a performance of the famous piece - Canon in D by Johann Pachelbel.This video's resolution quality is high, the performance itself is amazing.
