Regarding this column I have a slight question. Cecil says that it’s nescessary to be able to recognize a note on listening, and to sing it.
Is the latter part really nescessary? I’ve only ever known one person with perfect pitch (on everything, I can actually name an F and a D and their relative tuning but no other notes but that’s not perfect if it’s only two notes is it? ;)) he would tune the band when I was in middle school, as the assistant director(or at least the flutes, he worked with us most). But he didn’t sing at all he only played flute and piccolo in fact. He could obviously tune his voice to the note in his head without a reference pitch, but didn’t have the training to hit it dead on right away. Does this mean he did not in fact have perfect pitch? He could tell you easily if you were a few cents sharp or flat of the pitch but the singing seems to be a key part of the article.
And as for reading the score like a book (2nd to last paragraph). That doesn’t seem like a feat, when seeing music I can easily hear how it sounds exactly and I know I don’t have perfect pitch. That’s just an aside though.
