=== Groove classes ===
Mitchell Ohriner in "Flow: The Rhythmic Voice in Rap Music" describes seven "groove classes" consisting of archetypal sixteen-step accent patterns generated by grouping notes in clusters of two and/or three.<ref>{{Cite book |last=Ohriner |first=Mitchell |url=https://books.google.com/books?id=yAqlDwAAQBAJ&dq=flow+rhythmic+voice+%22groove+classes%22&pg=PA86 |title=Flow: The Rhythmic Voice in Rap Music |date=2019-08-01 |publisher=Oxford University Press |isbn=978-0-19-067042-9 |language=en |access-date=March 8, 2024 |archive-date=August 8, 2024 |archive-url=https://web.archive.org/web/20240808235058/https://books.google.com/books?id=yAqlDwAAQBAJ&dq=flow+rhythmic+voice+%22groove+classes%22&pg=PA86#v=onepage&q=flow%20rhythmic%20voice%20%22groove%20classes%22&f=false |url-status=live }}</ref> These groove classes are further distinguished from one another as "duple" and "nonduple". Groove classes without internal repetition can occur in any of sixteen rhythmic rotations, whereas groove classes with internal repetition have fewer meaningful rotations.
