It seems not a little ironic that Julie Andrews's most loved and well known performance, that of Maria in the Sound of Music, is probably her worst from the point of view of her singing, at least. Compare Eliza Doolittle and Queen Guenevere with Maria... Maria ain't up to as much.

By the way Mr Hammerstein (not that you're reading) when you wrote the line "So we put in words, one word for every note, like this. When you know the notes to sing, you can sing most anything." did you realise that you have three notes for the word "anything"? Perhaps you meant one syllable for every note?
