If you are on an Android device or an iPad with a TrueDepth camera, you will find the face gesture functionality in the Settings (tap the three dots at the top right corner of the library screen, then Settings), under Face Gesture Settings->Configure Gesture Actions. You can then pick which gestures you want to use, what actions you want them to trigger and you can test out the gestures by tapping the "Test Gestures" button. Once you have it configured, go back to the last screen and check the option to enable face gestures. Then you can load a song and test the gestures you assigned.
