What is OST? Why is OST often associated with movie songs? These are the questions that most users ponder when they first encounter them. Let's explore the meaning of OST in the article below.

1. Unveiling OST in the Musical Realm
In the realm of music, the term OST has become highly prevalent, yet few know that OST is an abbreviation for Original SoundTrack. It can be understood as film music, the original recorded soundtrack, or the prototype music from within the movie. This original music can be vocal or instrumental. OST is an integral part of creating timeless films. However, there are varied opinions on whether OST stands for Original or Official SoundTrack. Nevertheless, whether it's Original or Official, both interpretations carry a common significance.
OSTs often grace the pinnacle moments of a film, making scenes more impressive or appearing towards the end. These musical compositions are usually recorded separately, free from dialogues or other sound effects, allowing the audience to fully savor them. OSTs play a crucial role in films, contributing significantly to a film's success. A remarkable film is often closely associated with an exceptional OST. Sometimes, stumbling upon an impressive OST leads people to discover a particular film.

OST compositions are often intricately intertwined with the content of the film, following the main characters throughout the narrative. They act as a concise, evocative summary of the film, sparking curiosity in those who haven't watched and recalling memories of the most impactful scenes for those who have.
In the realm of films, a SoundTrack, or film music, is an audio recording created and used during the film's production or post-production. When a film is created, visuals, dialogues, sound effects, and music are initially separate, later combined to create what we hear and see in the movie. Apart from OSTs for films, there are also OSTs for TV programs, video games, and books. Some books even come with accompanying soundtracks, such as The Hobbit and The Lord of the Rings.
On YouTube, you may come across a title like 'A Boy Scribbles on a Tree | Mắt Biếc OST.' At that moment, you can understand that the song 'A Boy Scribbles on a Tree' is the musical composition for the film Mắt Biếc. Similarly, when listening to music on YouTube and encountering songs with 'OST' in the title, you can infer that those are background music for a specific film.
