Overture to Death:  The plot concerns a murder during a village theatrical performance; Sergei Rachmaninoff's "Prelude in C-sharp minor" plays a prominent part in the story. Prelude in C-sharp minor (Rachmaninoff):  It is a ternary (ABA) prelude for piano in C-sharp minor, 62 bars long, and part of a set of five pieces entitled "Morceaux de fantaisie"; and also known as "The Bells of Moscow" since the introduction seems to reproduce the Kremlin's most solemn carillon chimes.
