I've got to grips with Scientific Pitch Notation (e.g middle C is C4) but in a choral setting I am often confused because there seems to be a whole nomenclature where certain notes have specific names.
For instance "tenor high C" is C5, one octave above middle C. I've heard others mentioned but cannot remember their names and don't know what octaves they're in. Commonly someone will say "it's a D" and everyone else seems to know which D except me! And it seems to confuse everyone when I say "do you mean D4 or D5", or "an octave and a half below middle C"... which I guess is why those reference notes have names.
What are the names and pitches of the notes named for vocalists? Does this group of notes have a name in itself?
