Play Tone

Play a musical tone through pin P0 of the Calliope mini for as long as you say.

This function only works on the Calliope mini and in some browsers.

music.playTone(440, 120)


  • frequency is the number of Hertz (how high or low the tone is).
  • ms is the number of milliseconds that the tone lasts


This example stores the musical note C in the variable freq. Next, it plays that note for 1000 milliseconds (one second).

let freq = music.noteFrequency(Note.C)
music.playTone(freq, 1000)

Using other pins

Use analogSetPitchPin to change that pin used to generate music.
