I trust nowadays singers don’t give too much attention to a such valuable part of the singers “mechanism” as diaphragm.
I am delighted to share with you these brilliant videos where you can clearly see how powerful diaphragm is as a muscle and how significantly it can change size of our lungs and whole process of singing generally.
In the very beginning of trying to explore our vocal potential, it is essential to completely exclude the movement of shoulders whilst we are breathing. The majority of vocal teachers of the past emphasised the importance of involving the lower part of the lungs in the process of breathing for singers. From the point of view of human physiology it can be easily explained – lungs become wider at the bottom. If we do not breath “low”, firstly we will use only 50% of our potential in terms of oxygen. Secondly, it is simply impossible to then support our lungs and breath properly with the diaphragm (the muscles just under the lungs).
It is important to mention that after passing this stage you will face another obstacle – to find the right resonance for your voice. Release tension in your tongue, which is quite a strong muscle. Tension can affect your voice.
It takes time to find your own voice. You need to be true to yourself. It is so important not to give your voice extra weight or to have it too light. You will need to find the balance – ” chiaro scuro” , as Italian masters say ( light and dark). A sound that has a balance of overtones will fly, and will also allow singers built up a good vocal range.
