+# Analog Pitch
+
+Emits a Pulse With Modulation (PWM) signal to the current pitch [pin](/microbit/device/pins). Use [analog set pitch pin](/microbit/reference/pins/analog-set-pitch-pin) to set the pitch pin.
+
+```sig
+pins.analogPitch(440, 300)
+```
+
+### Parameters
+
+* `frequency` : [Number](/microbit/reference/types/number)
+* `ms`: [Number](/microbit/reference/types/number)
+
+### Example
+
+```
+pins.analogSetPitchPin("P0")
+let frequency1 = 440
+let duration = 1000
+pins.analogPitch(frequency1, duration)
+```
+
+### Some common notes
+
+* 440 = A4 on piano
+* see [piano key frequencies ](https://en.wikipedia.org/wiki/Piano_key_frequencies) for more information
