That last little ascending bit is harmonised, I think. (5ths?)

Other verse riff (alternate with the above):

  q  e e e q   e   sim.

At about 2:30 into the song, there's this bit, possibly as power chords:
E|-------------|-------------|-------------|-------------| (qtr. notes)
B|-------------|-------------|-------------|-------------|
G|-------------|-------------|-------------|-------------|
D|-------------|-------------|-------------|-------------|
A|----------5--|-7--8--------|----------5--|----------3--|
E|-5--7--8-----|-------8--7--|-3--5--6-----|-1--3--4-----|

Later, under "My corrupt crescendos...", there's a progression similar to
A5  C5  E5  D#5  G#5  B5, with some other little bits in there...

...but I don't know exactly how it goes--this sounds close, however.  I
believe the subsequent progression is
A5  Bb5  G5  F#5  |  A5  Bb5  G5  G#5

The "enter my funereality" bit is the same chord progression basically.

The cool arpeggiated ending bit which alternates with that above riff is:
Asus2  G#5  Gsus2  F#5

The ending riff is: (2 gtrs.)
