Shuffle series offers stable triple subdivision grooves.
Shuffles are generally rhythms in 4/4 time, in which each beat is sub-divided into three equal parts called eighth-note triplets.In shuffles and swing rhythms, the beat (one, two, three or four) and the let are accentuated to produce the feel.
Shuffles are a Fatback style, which means the second and fourth beats of the measure are accented. The bass and kick drum form most of their rhythmic ideas around the basic shuffle rhythm, with the snare drum sounding on two-and-four.
Blues is often played with a shuffle feel, at tempos ranging from very slow to very fast. Boogie-Woogie music has a shuffle beat, usually at a medium or faster tempo.
