Let's go back to the basics: posture! Since your body is your instrument, it's very important how you facilitate all parts of it to open up your breathing and resonating space while minimizing tenseness that blocks any part of your body that is involved in phonation. 

Standing straight - sure, you know you shouldn't slouch over while you sing. But what about your arms, legs, hips, head, neck, jaw? If you're like every other singer, you've experienced tenseness and strain on one body part or another while you sing over longer stretches. Creating the perfect posture will give you an ideal place to start from to let your voice act freely.
