What does hauteur réelle mean in relation to tubular bells?

[Mobius]

Hello,

I've been studying Ravel's orchestration for Mussorgsky's Pictures at an Exhibition and in the final movement (The Great Gate of Kiev) he uses a tubular bell in Eb. Underneath this, in brackets, it says "hauteur réelle" and I'm having trouble finding out its meaning. I did a Babel Fish translation but it translates as 'real height', which doesn't make much sense.

Does anyone here know what it means? [*-)]

Cheers,
Mobius.

Just a guess: "Actual pitch".

Thank you, I think you're right. I just consulted an old French dictionary that was gathering dust on my shelf of unloved books. [:)]
