How can I sound more confident?
Basically, you learn to "manufacture" confidence. Just as you would build a car or product. The concept of "Fake it till you Make it!" also applies. By working diligently on opening your mouth, throat and breathing, your sound immediately becomes more resonant, free and natural. Many people distort their natural voice. Have you ever had to tell a child to use their "indoor voice" or even chastise them for making a scene in public by speaking too loud? Using a "fake" or "polite" voice over a lifetime, many people have restricted the free, open and natural (LOUD) voice they were born with. There's a famous book called "Freeing the Natural Voice" - Linklater. I highly recommend it!
Think a moment about just how loud a baby's cry is... Nature enables even the smallest creatures the ability to call out to its mother. Have you ever heard a baby hummingbird's call? I like to make my lesson FUN and a true exploration of each student's natural voice. Often, great inspirations are achieved by imitating other people's voices, both speakers and singers, and animal calls. Our voices truly are amazing gifts to explore, expand and share with others!
