Breath Control in Singing
Any vocal coach will tell you that breath control in singing comes first and foremost, simply because the body of your voice relies on your breath. Without the proper posture, from spinal alignment to tongue placement, your voice would sound any combination of unflattering noises. It sounds like a lot to focus on at once, but as you practice, these exercises become second nature, and from there you can work on different styles, techniques, and registers.
