Question

how would you describe the beginning of holsts march in \mars, bringer of war\ (listen until 1:20)?
loud and forceful
ominous, slowly building in dynamics
a typical march in a major key
dynamically static

Explanation:

The opening of Holst's Mars, Bringer of War starts with quiet, repetitive, rhythmic motifs that create a menacing, foreboding atmosphere. It gradually increases in volume and intensity rather than starting loud, it is in a minor key (not major), and it builds dynamically rather than staying static.

Answer:

ominous, slowly building in dynamics
