How to improve your singing voice, you need to put your arms a bit away from the body in a relaxed manner when singing or hands may be clasped in front. This way the ribcage is free to expand and the lungs may fill up to its capacity. The more air means stronger and clearer voice.
Your feet should also be as far apart as the shoulders. One foot can be placed slightly forward. You need to be sure you are in total balance as you stand. Knees must also be a little bent. If sitting, the two feet should both be flat on the floor and one foot apart from each other.
