Cutting to soundtrack
Cutting to the soundtrack is when a scene relies on the soundtrack to carry the viewer's interest. The cut's made by the editor will be influenced by this music to get the maximum effect from the audience.It can be used with other sounds not just music, for example, if in a classroom the focus is on two people chatting and then we hear nails being scraped on a chalkboard, the next cut will be on the chalkboard.
Another example of cutting to soundtrack is matching the cuts with the sounds.Music videos and trailers are good for this because the editor can cut them to fit in with the sounds.

Choosing the right soundtrack for a movie is vital to get the correct look. Soundtracks could be everything for a movie like Guardians of the Galaxy which relies on their popular soundtrack to carry the movie.
When adding a soundtrack to a shot or scene, the editor will be given a list of songs to place at certain periods. Getting this wrong however can result in hilarious or disastrous consequences.
