But to be a master influencer, you need access to every part of your voice, because the sound waves you create enter the bodies of your listeners, triggering memories, feelings, and physical changes that determine how receptive they’ll be to you and your message. Just as the melody of a song creates the emotional soundscape that determines whether an “I love you” is an excited discovery or a longing goodbye, the melodies of your speaking voice, shaped and supported by your breath and the other elements that create your sound, send an instant emotional message.
