# Play Tone
|
|
|
|
Play a musical tone through pin ``P0`` of the @boardname@ for as long as you say.
|
|
|
|
### ~ hint
|
|
|
|
This function only works on the @boardname@ and in some browsers.
|
|
|
|
### ~
|
|
|
|
```sig
|
|
music.playTone(440, 120)
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* ``frequency`` is the [number](/types/number) of Hertz (how high or low the tone is).
|
|
* ``ms`` is the [number](/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)
|
|
```
|
|
|
|
|
|
### Using other pins
|
|
|
|
Use [analogSetPitchPin](/reference/pins/analog-set-pitch-pin) to change that pin used to generate music.
|
|
|
|
```blocks
|
|
pins.analogSetPitchPin(AnalogPin.P1);
|
|
```
