There are many incorrect answers for this, and some confusing drum tab. This is probably more of that, in some folks' opinions....
We are going to split this into its separate entities, mainly because I have a lot of other stuff to do, like fight child predation on PenUp, and plot against my enemies.
The rest of, Of Mind is replete with odd sequences like this.
Among the incorrect stuff were 3/4, 6/8 and 12/8, as stand alone notation, for this first section. None of those are actually correct.
7/? Time Signatures are basic stuff. Not easy as such, but 7/? Times command a groove that is the best of both worlds, being math, yet possessing a je ni ce quoi that prog metal must now understand, intrinsically. This is not a new thing in music, Rush was playing 7/16 back in the 1970's, and there's really no other (even) count, like 3, 6, and 12 counts, that will function in 7 times. That's the main reason this needed to be spelled out. The 12/8 following the first bar is a easy enough fit, and the 9/8 first and second endings could be notated in 3/8, enough said.
The Second PartNow, the verses that follow the section illustrated above are correct at 12/8 for a while, with the usage of ghost notes coming into the melody which this drummer deserves a hug for creating.... But, using two hands on the hi hat kind of forces you to clutch the correct ones, leaning on the hand/feet combos that are comfortable for you.
But, this is only a suggestion to developing a feel for what is going on in these measures; it is a lot.
If you're right handed, then you'll be seeking to match these notes on your right hand on the hihat, and right foot, playing 24 16th notes using both hands, and the above notation.
The Actual Count
This figure repeats, there are 3 more measures of 12/8, 1 15/8, 3 more 12/8, which then brings us to a culmination. This comes in the form of one and one 1/4 measures of 12/8, 16 beats in 4/4, which are composed entirely of a drum fill.
This fill takes the soundscape to the main verse's vocals. That lyric is, "There's a place within my dreams...."
You Can Break Me...
Wake Me Up
This is the downbeat count for each section of the Outro.
The Relationship Between The Hi Hat Ghost Notes on the Second Part of the Song, and the Outro's StructureThat relationship is in how the triplet phenomenon causes what appears to be a slight hesitation in those notes.
The key to understanding this is to regard these notes not as stand alone 8th and 16th notes, but, as the first, and the last notes of a set of triplets.
After using both hands to play the hi hat, and becoming proficient at clutching the hi hat correctly, then I would switch to the crash ride, or trash stack, or the ride, and play the hi hat notes with my left hand.
