With all this talk about voice range I have to bring a quote from J.J.Fux:
"One has to observe that the closer the parts are led together the more perfect the sound will be, for a power compressed will become stronger."
English is not my strong side but he seems to be talking about voice ranges right???
Anyways, I'm glad that there is this discussion because different theory books usually brings different ranges, which only add to your confusion!!!
It seems that when this book I'm now using "J.J.Fux, Gradus ad Parnassum" was written, the alto voice occasionally took the f below the middle c??? and sometimes even the e as well?! He mentions the original alto clef encompassing the range of the alto voice - which does include the low f - and then he suggest the notes outside this clef to be used occasionally- the e is just outside.
Was this because male voices were singing the alto parts?
In the same way, in only one example in the entire book does the soprano take the high a and g?!
Someone mentioned opera or solo singers capability of reaching notes off range - is there a standard to follow, or is this capability purely individual?
Perhaps what we are looking for is a good book about voice range, showing us the facts.
Does anyone know if there is such a book?
