The double stroke roll is a rudiment consisting of alternating diddles (i.e., RR, LL, etc.) of indeterminate speed and length. There are 10 official variants of the double-stroke roll (see below).

No.	Name	Notation	Description
6.	Double Stroke Open Roll		Like the single-stroke roll, usually played fast, but even when played slowly, alternating diddles are considered a double stroke roll. Played so each individual note can be heard distinctly.
7.	Five Stroke Roll		Two diddles followed by an accented note.
8.	Six Stroke Roll		Unlike most other double stroke rudiments, the six stroke roll begins with an accented single note. Then it is followed by the diddles and another accented note.
9.	Seven Stroke Roll		Three diddles followed by an accented note.
10.	Nine Stroke Roll		Four diddles followed by an accented note.
11.	Ten Stroke Roll		Four diddles followed by two accented notes.
12.	Eleven Stroke Roll		Five diddles followed by an accented note.
13.	Thirteen Stroke Roll		Six diddles followed by an accented note.
14.	Fifteen Stroke Roll		Seven diddles followed by an accented note.
15.	Seventeen Stroke Roll		Eight diddles followed by an accented note.
