Are you really saying that the operatic vibrato that most of the general population loathe so much (it's at least a very much acquired taste) is entirely natural?? ...
Clearly it's neither natural nor even necessary, since in 1910 the best singers used very little, just enough to warm the sound. My theory is that orchestras have got much louder since then, with the advent of metal strings and wide bore trombones and horns from the US, so that. in Wagner especially, singers use wide vibrato in a effort to distinguish the sound of the voice from that of the orchestral instruments providing similar frequencies. The way in which vibrato helps the ear separate the voice from other sounds is a known acoustic effect. It is less necessary in Puccini,[1] since he regarded an opera orchestra as something to show off the voice, and orchestrated appropriately, whereas Wagner wrote orchestral music with added voices. To be fair, Wagner's invention of the orchestral pit (at the Festspielhaus) with the brass well back from the opening to the auditorium,[2] coped with the balance problem in his own day, but he was unaware of the monstrous instruments that would be invented in the 20th C.
[1] AFAIK, the original "bel canto" composers, Donizetti and Bellini used smaller orchestras.
[2] The opening is about 1/3 the area of the whole pit.
