How is it POSSIBLE that one person can project their voice over a 60 piece orchestra?  The Singer's Formant!  The "Singer's Formant" is a set of specific resonance frequencies that allow classical singers to be heard over an orchestra.  The human voice can be trained to amplify resonances that are not amplified by other instruments that carry very well.  Some of the keys to finding the Singer's Formant include breath support, a lower larynx position, twang or squillo, and nasal resonance.  Even if your're not a classical singer, your voice will carry far better when your resonances have been trained to the fullest.  this can even be used to help the speaking voice carry over large crowds or far into the distance.  So, do the IMPOSSIBLE! Use the Singer's Formant!
