# play

Play a built-in melody.

```sig
music.baDing.play()
```

There are several built-in melodies which you can play in your game. When using blocks, a melody is chosen from a dropdown list. In JavaScript, an instance of one of the built-in melodies is referenced in your code. You call the **play** function from that instance of the melody, just like this:

```typescript
music.baDing.play()
```

Your program continues immediately after the melody begins playing. If you want the code that follows the **play** function to wait, you can use [playUntilDone](/reference/mixer/melody/play-until-done) instead.

## ~ hint

To understand how melodies are created for use in arcade, take a look at the developer [sound](/developer/sound) page.
