ok, little rant about a use of a leitmotif in les mis that i think has slipped under most people's radars!
so you the know the police leitmotif? the "tell me quickly what's the story/who saw what and why and where/let him give a full description/let him answer to javert!" tune that appears whenever somebody gets arrested?
now turn your ear to javert's suicide, specifically the "i am reaching but i fall/and the stars are black and cold" part. it took me a while to notice, but this whole section of the song is just a snippet of the arrest leitmotif:
but he never completes it. the snippet repeats and repeats. try as he might, he finds himself unable to sing the same old song of Justice and Law and Righteousness and Order. he's like a jammed cassette player spitting out the same second of music over and over and over and over again, unable to follow his old ways, but unable to let them go. he's stuck, but he will keep throwing himself against the walls of the cage.
javert is desperately trying to run on his old tracks of thought, but, as vicky h puts it, he experiences "the derailment of a soul, the shattering of an integrity irresistibly propelled in a straight line and dashed against God".
