“Pippin glanced in some wonder at the face now close beside his own, for the sound of that laugh had been gay and merry.
Yet in the wizard's face he saw at first only lines of care and sorrow;
though as he looked more intently he perceived that under all there was a great joy:
a fountain of mirth enough to set a kingdom laughing, were it to gush forth.”
- J. R. R. Tolkien, The Lord of the Rings
In this interpretation I think it would sound a little better if I read it faster, and also I would have the same mood as it mentions, like when it says "sorrow", I would like to sound sorrowful.
