Do singers have an optimum pitch within their tessitura (the range within which most notes of a vocal part fall) or would the their tessitura be considered the optimal pitches? I already know about vocal ranges, voice types, tessituras etc. However, an article I read made the question arise about optimal pitches. I've posted the link to the article below .
Yes, a singer would have a single optimum pitch. But it doesn't really matter.
The article suggests comfortably speaking a phrase, noticing the pitch, then applying that speaking technique to singing that pitch, then extending it to other pitches. So it's a shortcut to improving singing technique. A cute trick to get you to listen to yourself.
But there's no enduring value in knowing that one's Optimum Pitch is, say, the A below middle C. Speaking technique and singing technique are different. (That's why Schoenberg sometimes asked for Sprechstimme!)
