Coming Down The Mountain

 Non Diegetic - Inside characters head.

A Non Dietetic Music Soundtrack is played at the start of the clip which to me connotes his heart beat pace while thinking. (a non dietetic talking in his head voice over.) The words that he is thinking seem to give of a sense of annoyance and anger that he has a brother with disabilities.
then it goes onto apes as a imagination thought.

Diegetic- Everyone can hear.

Arguing - this to me connotes anger.
- Downcindrome boy appears in first scene with the camera view in Big Close Up to emphasize him looking at his food and the image is a shallow depth of field as it blurs the background.
Cupboard door opening - Sound Perspective - boy cant get any cereals as downcindrome brother was portrayed as selfish by eating 8 wheat a bix in one bowl, Mise en scene - breakfast meal with Average family in the kitchen arguing.this leads onto spoon in bowls - Sound Motif 1.07 - Breakfast.low key lighting with deep focus whilst the boy frames the father who appears to have a blank ignorant look suggesting this happens a lot.
car - Ambient Sound
slinky - Sound effect - connotes Boredom 
dad speaks - Diolouge
teacher speaks in class - incidental music
wouldn't it be nice song.- sound bridge - this connotes to me that he wishes his brother gone, with a sence of annoyance and see's his brother as a burden.
