I was wondering how you vibrate your voice when you sing(you know what i mean) I can do it just not very strong or long.
The technical term for what you are asking about is Vibrato. Vibrato is a naturally-occurring phenomenon that only happens when you have no tension in your throat, mouth, jaw, etc., basically the entire singing apparatus. Most people (myself included) go a step further and say that the rest of your body needs to be tension-free, as well. Vibrato is also present when you are breathing correctly, which is much, MUCH harder than it sounds. Only a good teacher or singing coach can really put you on the correct path for a free, open vibrato-rich sound! So, find a good teacher and work real hard and you will start hearing results….Good luck!
