The following video helps to explore and explain the cuperto exercise. An exercise that is useful in helping people find a good vocal tract alignment and get the thin edges of the cords engaged without interference from extrinsic muscles. It is an exercise used by Kirsten Flagstaff’s voice teacher, Allan Lindquest. This exercise is central to the work of the Swedish-Italian discipline of singing. I first learned this exercise when working with David Jones many years ago. He still uses it with students a lot. You can learn more about it via his website: https://voiceteacher.com/
