Exercises for vocal strains and cracks. I experienced the an expected throat pain in 2022 December, where I stopped singing because I couldn't and my voice became too deep. I stayed for a year battling with my voice and after I started getting better I noticed that everytime I'm singing my voice used to strain and cracks and I can't sing on all the keys I used to sing on. I still experience the strain and cracks and my vocal performance has become very poor, too much vocal tension and strain's. What can I do to solve it out?
