Music on Glo is optional and currently available on the website and iOS app.
You will find a music note on classes that offer music down on the play bar next to the volume icon (the play bar is where you can see your progress in a class and pause the class).
If you hover over the music note or click it you will see a control toggle appear.
If you move the toggle more towards Voice, you will hear less music for example. We will remember your setting for the next class!
If you click the music note again, you will turn off music completely.
