Foreboding- a fearful apprehension; a feeling that something bad will happen.

Just watched the original, silent horror film, The Phantom of the Opera (1925)!  So creepy, even though I had seen pictures of the phantoms 's face before seeing the film, the unmasking gave me a little start!  Great sets and silent acting.  A bit dramatic, but when you can't talk...

Also I scoured the internet looking for the score.  It's Franz Schubert's Piano Trio No. 2, Op. 100.  There are four movements total, but the one featured in the film was the 2nd movement.  It's great, the piano and strings take turns creating the foreboding march and the haunting melody.  Here is a link to listen on YouTube: Schubert- Piano Trio No. 2, Op. 100, 2nd Mov.
