Dear Concerned Schoolteacher,

This is a common problem with singing groups within schools.

Vocal technique can be compromised in attempting to achieve more volume. Merely telling students to 'sing louder' (regardless of the term used) will not get them singing louder correctly.

The key is to teach them the correct technique. Singing is a learnt skill and the right skills and techniques are required to achieve good volume and, in the long term, will promote vocal quality, longevity and prevent bad habits and vocal abuse.

Some of the skills required for good volume include correct breathing, torso support and breath control. The diaphragm does not actually contribute to volume. It cannot be consciously manipulated to achieve any singing effect. It merely lowers when inhaling and rises when exhaling. Although the lungs, diaphragm and the abdominal region are involved in the breathing process, the abdominal muscles contribute to volume.

Regarding the children's volume: at this stage in their development try asking them to sing so the person in the back row can hear them.

As the year progresses, if you constantly feel that they're too quiet, try amplifying them with a few well-placed microphones. This would be better than pushing their voices without good technique in place.

A good singing teacher will be able to lead you in the right direction and teach you the techniques required to acquire volume in a safe way.
