1.  As a foundation phase teacher, I would choose contemporary commercial music, because it encompasses all types of music, from pop to movie or commercial music.  I would choose this because, most or all the children will know it or be familiar with some of it.  The technology these days make it easier for children to know most of the music.  It  might be from a movie, saw it on the internet, like YouTube or they heard it on the radio.

2.  Yes, I think the examples and content in Study Unit 2 are inclusive.  I think Study Unit 2 covered all the information we should know about music.  I learned a lot from this Study Unit.  I learned from different types of music.

3.  For me I don't think Study Unit 2 needs changes.  It was an interesting Study Unit.  I learned a lot from Study Unit 2.
