Your voice is a horse, it has the courage, the freedom, the beauty, the crazyness, the heart; and as horses the fears, the shyness, the sudden scares and the sudden leaps. Us is the jockey, the rider that can train and understand the specific horse we have inside. We cannot change the horse but we can become excellent jockeys and trainers. Natural voices have no jockey and sometimes it is better than a bad one, no natural voices do not have perceived tha horse inside and they run at his place (not surprised it works not that well and you are out of pitch etc.). Good technique is knowing that we are two and teaching the jockey to train and give freedom to the horse, we always work on the jockey when we teach and only as a result on the horse.
