You don't play as Zelda, you can only play as link. Or in some parts you can play as WolfLink.
You didn't give enough information. Is the question how many Zelda games doesn't have Zelda's lullaby in the whole game or that you can play on the instrument?
Play Zelda's Lullaby
you learn it in the game after meeting Zelda
Zelda is a video game character.
Who cares. Only nerds play that game.
!Spoiler Alert! In spirit tracks after a guy steals Zelda's body her spirit takes over a phantom and you can move her. Also, there is a handful of crappy CDi Zelda games where you play as Zelda. But there so crappy they practically don't exist.
If by "Zelda Classic" you mean the original Legend of Zelda, you can play it for free at the link I have added.
Will Shortz will tell you that he thinks as many as 50 million people in the U.S. alone do the NY Times crossword, but I have no idea if he means daily, weekly, monthly or yearly.
