This is an important article. Pete Seeger and Woody Guthrie as well as Ronnie Gilbert and the Weavers all raised their chins while they were singing. This is a no no. Pete paid dearly for this by putting a strain on his cords.

The important part of good singing is to find the balance in your voice between the diaphragmatic breathing and the approximation of the vocal cords.

You don't need a lot of air, just the right amount of breath support.

This is why the bel canto people suggest pure vowels. It triggers the correct balance and response. This has to be monitored by a good vocal coach.

Above all, don't shout. This is what many pop artists do. Shouting over an orchestra is an unnatural habit.

"Don't talk in the car" is a warning not to shout over engine noise. Good advice.

A proper vocal setup can restore hoarseness. Above all, don't push! That's the real killer.

The Alexander Technique of relaxation is an important adjunct to singing or any musical instrument performance.

Alcohol and cigarettes dry out the cords. So do cough drops. Hot water with honey or tea seems to help facilitate smoothness.

Like any athlete, you have to warm up before performing. This is why there are vocal exercises. Don't go for high decibels when warming up. Coax the voice.
