Codes and Conventions in the use of thrillers

Conventions are decoded to relate to representation. They are broken down into four categories:

Speech: 

This is how a character has accepted and developed the narrative through the text. also they way in which he/she performed it.

Music:

The use of diegetic and non-diegetic sound is used to add to the atmosphere, realism, dramatic effect of verisimilitude.

Sound Effects:

How the use of these add to the realism of the scene. 

Editing:

This is how the 'flow' of the drama is aided by different editing techniques such as cross sits, fades, dissolve, jump cuts. etc. The use of these techniques add to the representational aspect of the broadcast.

A code is something that creates a meaning for the media text and can be split into two categories: 

technical and symbolic.

To conclude the use of codes and conventions for a thriller are very effective. The reason being is that the use of music and sound effects is that they can create a certain atmosphere, for example an orchestral church sound in a thriller, would provoke a feeling of tension and an uncomfortable atmosphere, which is generally what a thriller is meant to do to a member of the audience.
Another aspect of codes and conventions that I think can be used in a diverse and useful way is the speech. The use of speech in my opinion is that the less speech there is the more effect it has on the scene, the more tension and atmosphere it builds to create a scene of complete suspense and horror.
