Short Modulation From A minor to D# Minor. This is done using common chord modulation, in the last beat of the first bar of sheet 1 I use a V6 in A minor as a pivot chord representing N6 in D# minor.
good chords
When you play the song at abot 400 beats per second It kinda DOES sound like a modulation (or an Ubercharge) 
It sounds like a modulation in the original speed too.
The thing is it’s not really supposed to sound like a modulation, common chord modulations are designed to sort of “hide” the transition, and if you can only identify it at 400 bpm that means it’s an effective transition
