This was the scene:

In the scene two star-crossed lovers are hanging at the edges of an opening crevice, about to fall into the earth's flaming core. As they are hanging on opposite sides of the splitting Earth , they announce their strong love and their last vows for each other. FLAMES, FIRE, EXPLOSIONS shatter the scene in red, fiery, orange bursts. However, all the commotion is suddenly silenced, and all that can be heard is the serene sound of music and the desperate tone in the lovers' voices.

this is what I composed:

Lovers Over the Chasm, in 2 Movements
