various chords, chord progressions have certain feelings/moods..
yet there are tons of ways to create certain moods feelings using sound and music..experiment with chords/sounds and see how it makes you feel..
even just a drone(one note) on a synth can create a mood..sound effects also can do this..
if you want to create your own music..it could take a while and lots of practice but if you are just choosing music by other artists then my advise would be..listen to lots of examples and focus on the feeling they give you.and then find something appropriate..
