Someone is sending me YouTube links to videos of George Dragomir singing. Dear George, you have a good voice with a lot of potential, but you need to study with a tenor or someone who knows how to train tenors. Listen to and meditate on the vocal technique of Luciano Pavarotti. Listen especially to the vowels. Don't try to imitate his technique, but it will not hurt to imitate the vowels. A tenor must have ping, and the vowels will help. Remember Placido Domingo started as a baritone. Good luck. This is probably all I can do for you.
