MacLeod's description:

Genre: Soundtrack
Length: 1:45
Instruments: Orchestral - Bass, Cello, Violin, Celesta, Bells

Scant few cellos and bassists play pizzicato under celesta, bells, and violins in this slow and careful piece. The extra string tag on the end is not intended as part of the piece, it is included for use stand-alone in foreshadowing in video editing. 006
