Singing using your diaphragm?

You sing with support of your diaphram air pes the voice box and resonates in the sinus of the face. First, you have to understand how humans are meant to breath. We all breath properly when we are born and through time we start a habit of breathing using our lungs and shoulders. If you lie on the floor flat on your back and breath you breath correctly. When you breath in air enters your mouth and your stomach and chest rise but your shoulders do not rise. Your stomach rises because you have to think of your lungs as balloons when air enters a balloon it inflates and when it is let out it deflates. Now I have a great exercise for helping you feel your diaphram while singing. During your lesson I have the student place both hands on the piano stool and walk back with their feet until the are in a semi push up position. (not on the floor) You will feel alot of muscular tension in the abs where your diaphram is. It is nearly imposible to sing from the throat in this position. You will se an immediate difference in the quality and strenghth of your voice. This is exactly singing with the diaphram. Slowly, begin singing with the exact same technique in the relaxed upright position, feet slightly apart, arms at sides and knees unlocked. Note: Never sing out of your natural range. Singing incorrectly causes vocal nodes.
