You have a month to make an hour of soundtrack.
Up for the challenge?
Welcome aboard.
OST Composing Jam is back with another format, and this one's for those who can't get enough: you have one month to create at least one hour* of soundtrack of any genre for an imaginary game. Collaboration is encouraged to make one cohesive, complete soundtrack. You can find teams on our Discord server.
This jam will be unranked, meaning there will be no rating system, the main system will instead be giving feedback and comments. We also plan to organise a listening session of all the submissions at some point after the jam.
Hey there, and welcome to OST Composing Jam!
This is a place where musicians of all skill levels come together to write soundtracks for imaginary games just for fun, growth, and creativity. It started as a small idea and has now become one of the biggest music jams on Itch.io. Whether you're a seasoned composer or trying this for the first time, this is a space to explore storytelling through music, push your creativity, and be part of a supportive community of like-minded artists.

Note: The themes here are more like an inspiration, and strictly speaking there are no specific "musical theme" for you to follow and that you can compose in any genre you want, so the submissions can be as diverse as possible.
| How long? | *Recommended ~1 hour entire soundtrack combined, but no strict minimum duration - submit what you can! |
| How many tracks? | as many as your heart desire |
| What do I need to submit? | When creating the project on itch.io, you will need to upload the following:
• .mp3, .wav or .flac file of the track(s) OR use Scritch, a HTML media player you can embed directly on itch ○ The title of the file should also have your username on it (e.g. Lone Rabbit - Title Name.zip) • Either screen recording or screenshot(s) evidence of your DAW ○ Uploaded as screenshot(s) or mp4 file on itch.io ○ or as .pdf if a score on itch.io • Cover art (optional but ideal to differentiate your submission) ○ The cover size on itch.io is 630x500 px ○ If you are using the picture theme as your cover art, please always credit the artist in your description. ○ Please refrain from using AI-generated images. When submitting to the jam, you will be asked for the following: ○ Description of entry (e.g. genre, software, inspirations, your process, etc.) ○ Chosen theme ○ How does it fit the theme?

You can check out the previous jam's compilation album here!
