As a singer, one of the most frustrating things to experience is a vocal crack or break. These issues can occur when your voice is tired or overworked, or when you're not using proper technique. But the good news is that there are things you can do to fix vocal cracks and breaks and improve your overall singing voice. Here are some expert tips to help you get started:
Warm up your voice before singing. Just like any other muscle, your vocal cords need to be warmed up before you put them to work. Start with some simple scales and arpeggios to get your voice moving and stretched out. You can also try humming or singing "la" or "oo" on different pitches to warm up your vocal cords.
Practice proper posture and breath control. Good posture and breathing techniques are essential for healthy singing and a strong vocal range. Stand up straight with your feet shoulder-width apart and your shoulders relaxed. Take deep breaths from your diaphragm, expanding your belly rather than your chest. This will give you more air to work with and help you sing with greater power and control.
Experiment with different vowel sounds. The shape of your mouth and the placement of your tongue can have a big impact on your vocal range. Experiment with different vowel sounds.
Proper posture definitely helps when trying to sing. The way I found it helpful was when it reduced the strain on my voice when I was trying to hit those higher notes with power.
I am sure that posture is important, but seeing how I can only stand with assistance for a short period of time, I am proof that one can be successful without posture in the elimination of vocal cracks and breaks. Although, if one is able, I am sure it would make this goal easier.
