A page of snare drum rudiment practice phrases, written in 5/8, in a 3+2 phrasing. Keep this with your copy of Haskell Harr (book 2) or Rudimental Swing Solos.
These can all be played at normal rudimental tempos— quarter note = 105-126. You’ll probably have to set your metronome to give you 8th notes at 210-252 bpm for that. Or you can set it to give you downbeats only, at 21-25 bpm. The closed 7 stroke rolls are played with a 16th note triplet pulsation; the other closed rolls are played with a 16th note pulsation.
