Top Hat

Here we palm mute the root notes to the three chords in this song, C# A and B.

Intro cont.

Now we play the entire chord still palm muted and still with the same rhythm.

Verse

Same thing, still palm muted "The room is dark, my head is spinning..."

Chorus

Same chords, play 'em 4 times, just now we stop palm muting "I've got that long teeth, top hat..."

Verse

We're back to palm muting, this verse is twice as long as the other "I'll pierce your brain..."

Chorus

Same chords, play 'em 4 times, just we stop palm muting "I've got that long teeth, top hat..."

Bridge

This is where we start to change things up - different chord order, a different rhythm and I believe
it's played about 10 times starting at "you've got a sick, you've got a sick mind, boy..."

Outro

This might take a little work to nail the rhythm but it's not difficult. This riff starts when he sings
"I will drink your blood forever" the last four times at the beginning of that blood drinking stanza.
It continues until the end "A is for assholes, B is for backstab..." etc.
