Part 1. What is OST Music?

OST music stands for Original Soundtrack. It's the music you hear in movies, anime, TV shows, or video games—designed to match the mood, emotion, and story of each scene.

OSTs are more than just background music. They're carefully composed to enhance storytelling, build atmosphere, and make emotional moments hit harder.

Key Features

⭐ Scene-driven: Tailored to specific moments, like battle scenes, emotional dialogues, or dramatic reveals

⭐ Instrumental focus: Often features strings, piano, synths, or orchestral elements

⭐ Atmospheric: Built to set the tone—tense, dreamy, epic, or emotional

⭐ Memorable motifs: Many OSTs use repeated melodies(leitmotifs) linked to characters or themes

If you've ever had a movie scene stuck in your head because of the music, you've already experienced the power of a great OST.
