How do composers write music that makes us think of certain characteristics?

Composers compose music particularly because it can change the emotions of humans and how we think of the music to enhance our experience about music. Composers can attract other humans with their music because music is nearly everywhere in the world, there is always a day where people hear music intentionally or unintentionally.  First the composers think of music even though  it's hard and then they just get stuck on trying to find a piece then just out of nowhere they create music because of something they are inspired by. That's how some composers create music.
