# CreativeCodeChallenge: Sonic Pi Recursion

For this challenge, decided to recursion in an Audio sense.

Also being used as the foundational part for the[OST Composing Jam #4](https://itch.io/jam/ost-composing-jam-4) as the sounds fits the theme of "Runaway"

```ocaml
The name Sendoff was to represent a game where  the protagonist is running away but tells people that they were sent off. Problem with this tale is the entities that made them runaway are still chasing them.

Lurking in the shadows
no matter the path that you chose
don't know where you belong
but the entitles hunting don't care about right or wrong
Funny thing is, you have not seen what is chasing
and that is what makes the heart keep pacing
the body feel it has to still be escaping
What is it that you have taken
for these beings to be lurking in the shadows
```

Below you will find the code and the Audio created from those code pieces
