š¤ The 3 Sins of Vocal Training: Habits That Disconnect Your Diaphragm
When singers come to me for lessons, they often have good intentions⦠but also deeply ingrained habits that are quietly sabotaging their progress. I call them the Three Sins of Vocal TrainingĀ ā not because theyāre morally wrong, but because they physiologically disconnect the diaphragm, overwork the larynx, and stunt vocal growth.
These habits may feel āsafeā or even expressive, but in training, they create tension, instability, and confusion in the body. If you want to build a voice thatās free, powerful, and connected, these are the first things you need to stop doing.
ā Sin #1: Singing Softly in Practice
At first glance, singing softly seems gentle ā even healthy. But in training, singing quietly is deceptive. It often shuts down breath support and invites compensations higher up: the jaw tightens, the throat over-engages, and your sound becomes ungrounded.
What really happens:Your diaphragm disengages, airflow becomes shallow, and your body has no reason to build the muscular coordination needed for full, supported tone.
Train with clarity and intention, not caution.
ā Sin #2: Singing Breathily
Breathiness is often mistaken for emotion or subtlety, especially in pop and jazz styles. But in a training context, breathy singing is a technical dead-end. It encourages poor cord closure, leaky airflow, and bypasses the entire support system.
What really happens:The vocal folds stay too looseĀ to resist airflow properly. As a result, the diaphragm checks out ā and the throat steps in to compensate.
Sing connected. Then add air later ā if it serves the song.
ā Sin #3: Holding Back
This is the most common and dangerous of the three ā and the hardest to spot. Holding back can show up as:
singing with half-energy,
being overly careful,
tensing the face,
or just āplaying it safe.ā
What really happens:You short-circuit the bodyās natural breath-to-tone systemĀ and shift all the work to the larynx.
Full engagement is what builds freedom.
š What Connects All Three Sins?
They all have one thing in common:They shut the diaphragm out of the conversation.
Instead of letting your breath, support, and body do the work, you end up relying on the larynx ā a small, delicate structure that was never meant to carry the load alone.
š” What to Do Instead
Sing with full tone, even during warmups
Aim for clarity, not airiness
Practice with energy, not hesitation
Learn how to activate your supportĀ system on every phrase
And most of all:Train with curiosity, not fear.
