As a vocal coach, I encourage singers to have a plan of action with specific objectives when practicing to improve their singing. "What techniques am I going to practice today?"
Listed here are the techniques that you can practice to improve your singing.
There are many tools and vocal exercises to help you with this list. Its is important that you have an outlined agenda and plan of action to your warming up routine and practice time.
