# Play Tone
|
|
|
|
Play a musical tone through pin ``P0`` of the micro:bit for as long as you say.
|
|
|
|
## Simulator
|
|
|
|
This function only works on the micro:bit and in some browsers.
|
|
|
|
```sig
|
|
music.playTone(440, 120)
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* `Hz` is the [Number](/reference/types/number) of Hertz (the frequency, how high or low the tone is).
|
|
* `ms` is the [Number](/reference/types/number) of milliseconds that the tone lasts.
|
|
|
|
## Example
|
|
|
|
This example stores the musical note C in the variable `freq`.
|
|
Next, it plays that note for 1000 milliseconds (one second).
|
|
|
|
```blocks
|
|
let freq = music.noteFrequency(Note.C)
|
|
music.playTone(freq, 1000)
|
|
```
|
