THE BEAT

One bar, and 19% of the song

The beat the song is built on is one bar, played through bars 128, 130-131 and 133-158 -- 18.5% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.

Questions

What BPM is Sludge Factory?

83 BPM, in 4/4, with the time kept in sixteenth notes. The room plays it at any tempo from a quarter of that up to the written one, against the record where the record can follow.

Is Sludge Factory hard to play on drums?

59 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet. The beat itself is 13 out of 100; the rest of the number is everything around it.

How long is the drum part?

158 bars, about 7:33 at the written tempo. The course breaks it into 51 exercises over 14 sittings, about 26 minutes each.

What do I need on the kit?

crash, ride, hi-hat, snare, high tom, mid tom, floor tom, kick and hi-hat foot. That is most of a full kit; the part moves around it rather than sitting in one place.

How many fills are in Sludge Factory?

9 fills to learn, played 18 times: bars 8, 9, 25, 32, 33, 35 and 12 more.
