The term "additive rhythm" is also often used to refer to what are also incorrectly called "asymmetric rhythms" and even "irregular rhythms" – that is, meters which have a regular pattern of beats of uneven length. For example, the time signature indicates each bar is eight quavers long, and has four beats, each a crotchet (that is, two quavers) long. The asymmetric time signature , on the other hand, while also having eight quavers in a bar, divides them into three beats, the first three quavers long, the second three quavers long, and the last just two quavers long.
