This advert is a PlayStation 4 advert and the tempo is quite fast, energetic and speedy. This advert has used a range of different notes from high to low and it has a lot of Major Keys as its upbeat, makes your heart race and makes you want to play it, especially when the man in the advert starts to scream at you about it. The build up to it has quite a lot of minor keys to make it dramatic but it isn't sad and the diegetic sound is when the water hits the formula 1 car and when the horse screams. This advert has quite a lot of non diegetic sound because its animated a lot for example the voice overs, background music, a lot of spaceships flying around you etc.

This advert is an advert for Volkswagen. The tempo is quite slow and the keys are deep and long. It doesn't have a lot of major keys as its quite dramatic but not in a sad way dramatic, more to turn the listeners attention towards it so it has a lot of minor keys. The soundtrack doesn't have any diegetic sound apart from the car locking and the plate siding over to the kid but has non diegetic sound which is the soundtrack, the dog barking and that is it.

This advert is a CLS (sofa) advert and as you could of guessed the tempo is very slow, calming and relaxing as you'd want to feel from your sofa while sitting on it which is probably why they chose that sort of music. It has high key happy notes mixed in with minor slow notes which makes this piece of music very upbeat but calming at the same time which is perfect for a sofa advert. It has no diegetic sound but has lots of non diegetic sound including the soundtrack and voice over.

This is the coca-cola advert which comes on to your screens around Christmas time. The tempo is fast and happy as you'd expect from a coca cola advert trying to get people in the mood for Christmas. It doesn't really have any minor keys but has lots of major keys. Again this advert has no diegetic sound but has lots of non diegetic sound which is the music and the voice overs in the advert.

This advert is an advert for Calvin Klein where Justin Bieber is playing the drums and posing with Lara Stone and this is where the tempo comes in because the only soundtrack is Justin Bieber playing on the drums but the tempo is very fast and this is where the diegetic sound comes in because it has both diegetic and non diegetic sound as you see Justin playing the drums but then it cuts to the bit where he isn't playing it and the sound carries on. it doesn't have any minor keys in the advert but has major (happy) keys.
