# Analog Pitch
Emits a Pulse With Modulation (PWM) signal to the current pitch [pin](/device/pins). Use [analog set pitch pin](/reference/pins/analog-set-pitch-pin) to set the current pitch pin.
Emits a Pulse With Modulation (PWM) signal to the pin ``P0``.
Use [analog set pitch pin](/reference/pins/analog-set-pitch-pin) to set the current pitch pin.
```sig
pins.analogPitch(440, 300)
```
### Parameters
## Parameters
* `frequency` : [Number](/reference/types/number)
* `ms`: [Number](/reference/types/number)
* `frequency` : [Number](/types/number)
* `ms`: [Number](/types/number)
### Example
## Example
```blocks
pins.analogSetPitchPin("P0")
pins.analogSetPitchPin(AnalogPin.P0);
let frequency1 = 440
let duration = 1000
pins.analogSetPitchPin(AnalogPin.P1);
pins.analogPitch(frequency1, duration)
```
