Perpetuum mobile

A well-known example as a technique is the presto finale of Frédéric Chopin's Piano Sonata No. 2: This figuration of rapid triplet quavers (eighth notes) continues for the duration of the movement.

In music perpetuum mobile (Latin, English pronunciation /pəːˌpɛtjʊəm ˈməʊbɪleɪ, ˈməʊbɪli), moto perpetuo (Italian), mouvement perpétuel (French), 'movimento perpétuo' (Portuguese) movimiento perpetuo (Spanish), literally meaning "perpetual motion", has two distinct meanings: pieces of music, or parts of pieces, characterised by a continuous steady stream of notes, usually at a rapid tempo, or whole pieces, or large parts of pieces, which are to be played repeatedly, often an indefinite number of times.
