I am a disciple of Professor Gregg Breinberg from the United States. I teach how to make your vocal chords stronger, tuning and lots of fun with a variety of songs. As for instruments, I have a guitar course, but my specialty is music. I learned a lot from singers. Using an object in the mouth, such as a pen, to make the vocal cords stronger. Training for tuning, use of mineral water to improve performance and finally the most enjoyable part, which is practice. Wait for you!!!!
