ring Tone

Play a musical tone on the speaker. The tone has a pitch (frequency) as high or low as you say. The tone will keep playing until tell it to stop.


Simulator: ||music:ring tone|| works on the Adafruit Circuit Playground Express. It might not work in the simulator on every browser.

The tone will keep playing until you stop it with ||music:stop all sounds||.


  • frequency is a number that says how high-pitched or low-pitched the tone is. This number is in Hz (Hertz), which is a measurement of frequency (pitch).


Play a tone with a base frequency of 440 but change it by 20 Hertz steps both up and down.

let offset = 0
offset = -100
while (true) {
    while (offset < 100) {
        offset += 20
        music.ringTone(440 + offset)
    while (offset > -100) {
        offset += -20
        music.ringTone(440 + offset)
