The Most Common Vocal Problems
Most singers tend to struggle in one of three ways:
Squeezing or straining on high notes
A breathy or weak sound, often accompanied by running out of breath on phrases
Difficulty connecting the different parts or “registers” of the voice
Sometimes all three at once.
While these problems can feel completely different, they are often connected underneath.
The Key Areas Behind Most Vocal Problems
In simple terms, singing relies on the coordination of three main things:
Breath flow
Not just breathing deeply, but controlling the flow of air moving from the lungs and through the vocal cords.
Vocal cords coordination
How firmly the vocal cords come together, how strongly they resist airflow, and how efficiently they vibrate to create sound.
Vowel and larynx
The shape of the mouth and position of the tongue both have a major impact on resonance, larynx behaviour, airflow, and vocal freedom. This is the part many singers overlook.
All of these elements affect tone, volume, resonance, stability, and vocal colour.
Small Changes Create Big Differences
These elements constantly affect one another – nothing works in isolation.
For example:
airflow affects vocal cords behaviour, and vocal cord behaviour affects airflow
vowel shape affects vocal cord coordination, and vocal cord coordination affects vowel shape
vowel shape affects resonance and airflow, whilst airflow itself can also influence resonance and vowel shaping
These relationships are bidirectional.
Because of this, singers often try to solve the symptom rather than the underlying coordination problem.
When these elements begin working together efficiently, the voice becomes more reliable, flexible, and expressive.
The Missing Piece for Many Singers
For centuries, singing instruction focused heavily on breathing and diaphragm control. Modern vocal science and contemporary vocal training have shown that vowel shaping – including mouth shape, tongue position, and larynx behaviour – plays a much more important role in vocal coordination than was once understood.
That’s why good singing, and effective vocal training, are rarely about forcing harder or singing louder. More often, it’s about making precise adjustments that allow the voice to work with itself rather than against itself.
