Practice low notes to sing high notes.

Practice low notes to improve your ability to sing high notes. Now this may sound like an oxymoron but its not. In this video, I explain the science behind practicing low notes. I also demonstrate how to practice low notes.
Your vocal folds are muscles in your throat, right behind your adam’s apple. They are responsible for voice production with support from proper breathing. When you practice low notes, your vocal folds are loose. When you sing high notes, your vocal folds are tight. Your muscles get stronger when you relax them and stretch them and you do this exercise repeatedly.
