Singing is not that difficult and everybody can learn to sing. I have divided the singing techniques into four main subjects as listed below. By combining elements of these four subjects, you can produce precisely the sounds you want. You will also be able to pinpoint your specific problems and mistakes, and you can focus on which techniques you wish to work on.

The four main subjects are:

• The three overall principles – to ensure healthy sound production

• The four vocal modes – to choose the ‘gear’ you want to sing in.

• Sound colours – to make the sound lighter or darker.

• Effects – to achieve specific sound effects.
