Hi, Jenny S. I don't believe in chakras, but like many here, I have experienced that feeling of singing at peak ability (incredibly well, as you say) and having everything about the experience seem at its best - a peak experience. For various reasons, I don't think it's something that can be turned on or off, lost or found, since it involves factors like how my sinuses are that day, something out of my control. I do think the peak experience comes from the love of the song and the singing, and also from being so comfortable with the act of singing that it flows without having to think about it. When the acoustics are good, I can hear the results, which feeds back in to the heightened experience. I've heard various visualization symbols that are sometimes taught to try to get students to improve tone... like a fountain bubbling up from the top of the head, or a spot in front of the forehead that the sound is going out to.... in my opinion, these things are not to be taken literally. They are simply symbols to try to see if that helps in placing the sound in resonating chambers that affect the tone. What is most real to me is the emotion I feel in connecting with the lyrics and also how the melody feels to sing. When I really love the song, it makes it possible to have a peak experience singing it.
