Let's ring in the new year drummer-style, by complaining about a Charley Wilcoxon book maybe two or three of you own, Rolling In Rhythm! Even without the book, there's something to be learned about archaic drum notation, and rudimental-form rolls, and drum notation generally. It's funny, remembering that much of George L. Stone's Technique of Percussion, written 70-90 years ago, is dedicated to this same problem of interpreting drumming notation. Apparently it's an eternal thing.
See my 2018 post All About Rolls if there's any confusion about the terminology in this post.
Rolling In Rhythm should be the ultimate book on rudimental rolls, especially in that swing-era type of phrasing, best known to us now through Philly Joe Jones's playing, and a lot of other bop drummers. It's a 30s thing that was a dominant form of soloing and filling in jazz for another 30-40 years. Unfortunately, the book a mess. There is a lot of bad, archaic notation in it, which is not aided in the typo-riddled edition by Richard Sakal, which seems to be the only version available now.
The pages covering 10-stroke rolls and 11-stroke rolls are especially egregious— pp.24-26.
We commonly encounter both of those roll types in triplet form in the piece Three Camps, either as two beats of triplets* with an accent at the beginning, rolling on the remainder:
* - Since the example is in 3/8 time— a compound meter— these are not actual triplets— they are played with a triplet feel, however. I say triplets here for convenience, because that's what the same rhythm is in 4/4, and 4/4 is a familiar point of reference, and triplet is the familiar term for notes played with that feel. When the time signature has an 8 in the bottom, if I say triplet, I mean 8th notes played in a triplet feel. Compound meter 8th notes.
Starting with an accented single, the 11-stroke roll above would be called a “tap 11.” Another form begins with the roll on the downbeat:
So far so good. Things begin going off the rails in the next line, with this oddly-displaced 11-stroke roll:
First, the editor put the time signature as 6/8, but put the actual barlines in 3/8. I scratched out the extra barlines and added a beat of rest at the end to make it actually 6/8. No big deal. He also put the wrong sticking on beat 2 of the third measure. OK.
Again, the first four measures, and the last two measures, are each intended to be played the same. The last two measures are fine; it's a tap roll at 16th note rate— although 96 bpm is rather fast for that.
PROBLEM: Making the above roll at a 16th note rate displaces that last 8th note to fall on the last 16th note of the measure:
The purpose of that is to produce a quality roll at tempos where it's difficult to do that at more normal pulsation rates. It's a good thing to practice, but it's not what's intended with the book, so you'll be creating inconsistencies within the book materials. If you follow the screwed up archaic interpretation, at the book materials will be consistent within themselves.
