Hi I'm 10 and I want to sing higher and louder when I do my voice cracks I've beek practicing for months nothing happens what do I do?|||It seems obvious that you have incorrect singing %26amp; breathing techniques. The only SAFE way to learn these is to consult a fully trained vocal teacher, just to avoid vocal nodules, hoarseness and other nasties that will develop over time if you continue singing incorrectly.|||Not everyone can sing high. Maybe our an alto? (Altos sing the lower notes) But singing lower notes can sound just a beautiful as high notes.|||Drink lots of water and try singing from the stomach. Not From your throat.
