Understand why your voice is cracking. A voice crack is most commonly associated with a boy entering puberty, which can occur any time between the ages of 10 and 16. Some boys will pass through puberty and never notice vocal cracking, while others will experience it for long periods of time. Depending on your age and your circumstances, your voice may be cracking for a variety of reasons, some of which are manageable and some of which need to be waited out.^[8]

Rock singers who actually scream during a number can damage the vocal cords over time. Both will cause a cracking voice. Allergies to milk products will cause this problem, and also Thyroid disorders may cause changes in voice, especially if the voice is getting deeper, cracking, or you are having problems with swallowing. May 03, 2019  If by a crack you are talking about putting a ‘sob’ in your voice for an emotional device in a song, you can very quickly stop your breath and retstart it again on the same note, using a tiny bit of voice as you start the breath back up. Vocal cracks can be caused by a number of things including: Muscle weakness surrounding your vocal folds. Not warming up properly before you sing. Too much tension in your body. Not enough airflow coming through your instrument. Vocal placement – this means where you are resonating the sound in your instrument.

How To Not Have Voice Cracks When Singing

• When boys go through puberty, the testosterone production is increased drastically to promote rapid growth in the body, the larynx (or 'voice box') included. When the larynx gets bigger, the voice becomes deeper and more resonant, but it can take a while for the body to get used to the rapid changes. Eventually, your voice will settle into its new, and usually deeper, range.
• For girls, vocal cracks most commonly occur when the voice is strained during singing or from other periods of intense usage. Risky behaviors like smoking and abusing alcohol can also put a strain on the voice, resulting in the occasional crack. Strengthening the vocal chords via singing exercises and eliminating risky behaviors is the best way to avoid vocal cracking.
