If you have a private voice teacher he or she is probably always telling you butt! pallet! diaphram! ribs! If you dont have a teacher you are going to be looking quite puzzled right now, so let me explain it. Lets start at the top and work our way down. First we start with the high eyebrows/bright eyes; this is important because it helps you to raise your soft pallet which helps get you higher notes and better tone, because the air has more room to come through. Next as we come down its the nose; you nose must be closed off like you are swimming and dont want water to get up your nose. This makes it so that you dont sound all airy like some of the now a days pop stars and it controls the squeak on high notes. In your mouth alone there are about a hundred things a pettifogger could come up with to tell you; but lets just stick to the more important ones. Your pallet needs to be high, your tounge should have a groove in the middle and when you sing it should feel like you are singing a oouuu. The mouth has a couple settings: wide and tall...you want your mouth to be very tall- able to stick at least two fingers width inside. This will give you a more rounded and less screachy tone. A little tip to tell if you are on pitch is to cup your ear and listen to the note, it makes the sound resound in your ear inableing you to tell if you are on the same pitch. Next moving down to you arms and hands, they should be at your side. Your ribs are actually quite important they really have to be out otherwise you will sound breathy and your range will not be as high. Singing really is a workout- you must have your stomach muscles in action so that you can sing from your diaphram. You must always sing from down low, you will damage your throat and larynx and such if you try to force sing from the top. Now for butt; no this is not a joke. Scrunching your rear will help you to tighten your stomach muscles and use your diaphram in the most affective way. It will also help with you posture which of course is very important for any singer not just because it gives you more roo, but also for stage prences. Locking your knees is an absolute NO! If you do this you can block air circulation and cause yourself to pass out. Believe me this has happened a couple times in a few of my choirs. Standing with your feet about shoulder width will also help you because it provides you with a better base and if you are nervous on risers you are less likely to fall. Put most of the weight onto the balls of your feet without lifting your heels from the floor. This helps again with posture and not locking your knees. This is a little over view of what you need to learn to become a singer. If you are really interested in doing singing you will need to find a private voice teacher who will tell you all of this and help you to install all of this into your brain. Have fun.
