Aside from captivating visuals, often the music accompanying a scene in a movie or TV show is what gives the audiences emotions that extra kick to build up and spill over when watching. A lot of work goes into making a soundtrack for a movie: licensing songs, producing and recording, as well as composing powerful, fitting, and rememberable scores. If you take a look at many iconic theme songs from popular TV shows and movies through a musical lens, you’ll notice a very interesting common theme. In music theory there are musical scales called modes. Modes are similar to regular scales in the sense that they are sequences of notes with distinct relative distances between the notes. However, modes are permutations of regular scales. A regular scale as 7 notes in it, meaning that there are seven possible modes that can branch off from the scale. There are several types of modes including Dorian, Ionian, and Aeolian all which follow a specific ascending and descending sequence of notes. For example the Dorian mode follows the patter, whole, half, whole, whole, whole, half, whole in ascending order from the root note. An easy way to look at modes is to see that scales and their modes contain the same notes, modes just use different root notes.
