I've never had formal vocal training, but I do know that the secret to good singing is using your diaphragm to support the air. The diaphragm is a muscle (apparently) beneath the lungs, which is used by singers, and players of wind instruments to get full value for the air in their lungs. If your tummy goes IN when you breath in, you're doing it wrong. Make sense, if you thing about it. When you breath in a full load of air, your tummy, should, by rights, expand. And then when you breath out, you'll find you can breath out longer by squeezing your tummy in, forcing the diaphragm to push much more air out of your lungs. This will result in longer notes that sound less strained. The tenor in this illustration is demonstrating an artificial means of enhancing the diaphragm and producing beautiful, sustained notes by using my latest invention, the hand-operated Diaphragm Augmenter.
Please be in touch if you would be interested in beta-testing this device, once I make up a working prototype!
