By the way, DT is always switching up subdivisions in their solos/riffs. Like, they'll be playing 16th notes, then a burst of sextuplets, then back to 16th notes, then onto a blaze of 32nd notes, etc.
But in that example, you could keep the "1" the same all through those subdivisions. And the same tempo/time signature.
But with this riff (if you rewind the video above), most of the riff has a triplet feel, in 4/4 time. But in 3 measures of that riff, they switch to 3 groups of 6 notes, which you can't really continue counting across 4 beats.
I've only seen this very few times. You either keep counting in 4/4, so you can retain the triplet feel as you're playing, and just blaze through those 18 notes in each of those 3 measures, and get it to the point where you come out of it on "1", or...
You change the counting, and the tempo, to either 8th notes @ 220 bpm, (which would change the time signature to 6/4), and count those 18 notes as 6 triplets, or go to 110 bpm, and count them as 16th notes and sextuplets. Those would be the only way you could keep a consistent beat across all measures.
Actually, you could play it in 4/4, but count it in "2", giving it a Waltz feel, 1 2 3 4 5 6, 2 2 3 4 5 6, counted One_And_Two_And, and when those other measures come up, you layer half-note triplets (total of 6 notes) over the 1 & 2 &, but "triplify" each of those 6 notes. 6 X 3 = 18.
If that makes sense.
And really, at the end of the day, the more I mess with it, the more I can just "feel" my way through it, without needing to have any consistent anchoring beat. Even if I'm nowhere near the tempo. It's a very cool change of subdivision for sure.
right before the big finale.
