# Ring Tone
|
|
|
|
Play a musical tone through pin `P0` with the pitch as high or low as you say.
|
|
The tone will keep playing until you tell it not to.
|
|
|
|
## Simulator
|
|
|
|
This function only works on the micro:bit and in some browsers.
|
|
|
|
```sig
|
|
music.ringTone(440)
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* a [number](/reference/types/number) that says the tone's
|
|
**frequency** (how high-pitched or low-pitched the tone is). This
|
|
number is in **Hz** (**Hertz**), which is a measurement of frequency
|
|
or pitch.
|
|
|
|
### Example
|
|
|
|
This program checks the **accelerometer** for the micro:bit's
|
|
**acceleration** (how much the micro:bit is speeding up or slowing
|
|
down). Then it uses that acceleration to make a tone. If the micro:bit
|
|
speeds up, the tone's pitch gets higher, and if it slows down, the
|
|
tone's pitch gets lower. It's fun -- try it!
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
music.ringTone(input.acceleration(Dimension.X))
|
|
})
|
|
```
