Perpetuum mobile
Perpetuum mobile means, two different things in music. One is a kind of piece of music, which is usually played in a fast tempo, and which consists of many short notes. The other is a piece of music that is played over and over.
Composers who used this name include Niccolò Paganini, Carl Maria von Weber and Felix Mendelssohn.

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.
