Moore: "By the 1940s was a trend toward the use of what Peñalosa calls the 'offbeat/onbeat motif.' Today, the offbeat/onbeat motif method is much more common." With this type of guajeo motif, the three-side of clave is expressed with all offbeats. The following I IV V IV progression is in a three-two clave sequence. It begins with an offbeat pick-up on the pulse immediately before beat 1. With some guajeos, offbeats at the end of the two-side, or onbeats at the end of the three-side serve as pick-ups leading into the next measure (when clave is written in two measures).
