When Claude and Quasimodo went out together, which frequently happened, and when they were seen traversing in company, the valet behind the master, the cold, narrow, and gloomy streets of the block of Notre-Dame, more than one evil word, more than one ironical quaver, more than one insulting jest greeted them on their way, unless Claude Frollo, which was rarely the case, walked with head upright and raised, showing his severe and almost august brow to the dumbfounded jeerers.

In his voice was an old quaver which was not habitual and there was agitation in every line of his visage.

Someone was singing, a dull, old, droning sailor's song, with a droop and a quaver at the end of every verse, and seemingly no end to it at all but the patience of the singer.
