Also sometimes referred to as "critical timing".

The idea behind the rolling count is that between the beats (1-2-3-4...) we can imagine smaller "subcounts" that are typically called "and" and "ah", and associate certain actions with them (see below).

The counting then becomes 1-and-ah-2-and-ah-3-and-ah-4...

The exact timing of "and" and "ah" depends on the music and the personal style.

Typically, the actions associated with counts (1, 2...), "and" and "ah" are:

• Count: the foot strikes the floor. The amount of weight that is transferred immediately depends on the personal style, and is usually between zero (no weight transfer) and 50% ("split-weight").
• "and": transfer of the the rest of weight.
• "ah": the hip release, the preparation for the next step, possibly a pivot.

Rarely an additional "eh" moment is identified, making the count 1-eh-and-ah-2-eh-and-ah-3... The function assigned to this additional moment varies.
