A pronounced singer's formant is important for a singing voice, because frequencies around 3000 hertz (pitch) play a decisive role for the viability of a voice. This means that the singer's formant is well marked, stand out in a sung note when the frequencies between 2800 and 3300 Hz are relatively strong, regardless of the fundamental frequency. With frequency components in the singer's formant there is a trained singing voice possible, to prevail against noise and against a larger orchestra.
