Fortepiano (dynamic marking)

Fortepiano is a dynamic marking used to denote an accent or stress in the music by suddenly being loud (forte) and then immediately soft (piano). The marking is written as “fp” directly underneath the note where it occurs. This marking appeared frequently in the eighteenth century as a more flexible system of dynamics was forming. In this example from Paisiello’s overture to Il barbiere di Siviglia, the fortepiano is heard every few seconds from the whole orchestra. This concept should not to be confused with the fortepiano, a keyboard instrument from the eighteenth century.
