Witherspoon was right.
The chief danger in learning to sing is fussing too much with parts.
We live in an age obsessed with controlling the voice.
The Old Masters “cultivated” the voice; they did not go in for “voice production.” Check out the wording on treatises of the 19th century. Books written early on discuss the ‘cultivation of the voice.’ Later books focused on ‘voice production.’

We are NOT machines. We are human beings. You cannot push buttons to make a voice work better.
Until we honor and acknowledge the organic nature of the singing voice and stop trying to locally control everything, we will unable to find a pedagogy built upon respect for our fellow human beings and the wisdom of their bodies and throats.
