So your voice is breaking, and you'd like to learn how to fix a cracking singing voice... but it's tough, right?

Connecting chest and head and singing without breaks is actually one of the most basic fundamentals of all great singing, and absolutely the most important.

I'm going to show you how to connect chest and head in a moment, but first, let's work out WHY your singing voice is cracking and breaking.

Now, there's actually two different muscle groups that control the coordination of your vocal folds; we call the resulting 'registers' that occur when you contract either of these muscles "Chest Voice" and "Head Voice".

Now, these terms are totally incorrect in a functional sense; your voice doesn't really resonate in either the chest OR the head - your main vocal resonators are the Oral, Pharyngeal and Nasal resonators, all existing within the vocal tract above the vocal folds.

The first of these muscles is the Thyroarytenoid, or, the "TA" muscles. These muscles actually make up the body of the vocal folds themselves, and when contracted, literally contract the vocal cords to create thinkness, weight and depth; both in a physical sense and also a tonal sense too. We all love the sound of a rich, full Chest Voice, right?

And here's where most people go wrong; they dig the sound of their chest voice, but can't stand their weak, breathy head voice (sound familiar?) - so, when they sing high notes they try to force their chest voice higher and higher to the point where their voice breaks.

Literally, your vocal folds are too thick and contracted to vibrate at the high speed needed for the high note you're trying to sing. At this point, you either strain your voice; or you flip into falsetto.

The true key for how to fix a cracking singing voice is actually to stretch the vocal folds using the Cricothyroid, or, "CT" msucles. These muscles are located underneath the larynx and when contracted, they tilt the larynx and stretch the vocal folds long, thin and tight to facilitate the fast, easy vibration required for singing high notes - unfortunately, this means you lose much of the 'weight' that you enjoy from your tone in chest voice, and instead of developing this muscular balance; most beginner singers simply avoid the CT muscle completely and either try to yell higher when the go for high notes, or, the simply flip into falsetto.

The key here is really to use BOTH of these muscle groups at the same time; partially contracting the vocal folds while stretching them at the same time - resulting in easy high notes that are full of power, depth and beauty.

The reason your voice is cracking is because you haven't yet developed an antagonistic relationship between the TA and CT muscles to create what is often called "mixed voice" - a mix of resonance of both your chest and head voice, and a mixed use of these two muscle groupings.

The first key to developing your mixed voice is to connect your chest and head voice by handing off smoothly between TA dominance and CT dominance - basically, fluidly moving between weight in the folds to length in the folds while maintaining vibration and connection without flipping of breaking.
