In [[20th-century classical music|20th-century concert music]], it became more common to switch metre—the end of [[Igor Stravinsky]]'s ''[[The Rite of Spring]]'' (shown below) is an example. This practice is sometimes called ''[[Mixed meter|mixed metres]]''.

A [[metric modulation]] is a [[modulation (music)|modulation]] from one metric unit or metre to another.

The use of [[asymmetrical rhythm]]s – sometimes called ''[[aksak]]'' rhythm (the Turkish word for "limping") – also became more common in the 20th century: such metres include quintuple as well as more complex [[additive meter|additive metres]] along the lines of {{serif|2+2+3}} time, where each [[bar (music)|bar]] has two 2-beat units and a 3-beat unit with a stress at the beginning of each unit. Similar metres are often used in [[Bulgarian dances|Bulgarian folk dances]] and [[Indian classical music]].
