To yodel, one sings a scale continuously upwards, until one's voice "breaks" (switches octaves) into one's "head voice" (also known as falsetto in men). This point is one's "voice break". Then one must go back down a note, and up again, over the voice break. This is done repeatedly at a loud volume.
In "Hodl - Ay - EE - Dee", the "EE" switches to the head voice.
