Unbelievable help! I am preparing for an amateur performance for a loved one and have never performed solo live before… as I have been recording lessons and practicing I can hear a DRAMATIC change in my tone… I feel great about the changes within just TWO lessons– David knows exactly how to troubleshoot weak spots in your voice QUICKLY! I really look forward to lessons as it is a very rewarding experience and David makes you feel very comfortable quickly. FIVESTARS highly recommended! Bring something to record lessons as afterwards you can really hear the change in voice from amateur to a more pro sound!
