My first draft of the song didn’t feel very heavy, the second half of the song felt boring and too similar to the first and the song didn’t feel scary enough. I decided to make the bassline in the second half more dissonant nearer the end of creating my track which helped create more variation. I also decided to use parallel compression on the drums and bass to make them sound heavier.
Structurally I added in several bars between the sections as small transitions as well as some hi hats with delay on at the beginning of the track which I think added to the song, It gives the song more of an more of an identity.
