## Introduction

`melrōse` is a tool to create and play music by programming melodies.
It uses a custom language to compose notes and create loops and tracks to play.
This is an example of a simple major scale C.

```javascript
sequence('c d e f g a b c5')
```

Note sequences in your program can be changed while playing giving you direct audible feedback. 
For the best experience, use the `melrōse` tool together with the Visual Studio Code Plugin for Melrōse.
