Sudden changes in dynamics are notated by a s prefixing the new dynamic notation, and the prefix is called subito. Subito is italian as most other dynamic notations, and translates into "suddenly"[1]. It is usually used along with forzando (italian for "forcing"), to make subito forzando, or what most people refer to as just sforzando. Other common uses of subito are before a regular dynamic notation, like in spp, sf, or sff.

Sforzando (or sforzato), indicates a forcefull, sudden accent and is abbreviated as sƒz. Regular forzando (fz) indicates a forcefull note, but with a sligthly less sudden accent.

The fortepiano notation ƒp (or subito fortepiano; sƒp) indicates a forte followed immediately by piano. This notation is usually used to give an unusual strong (and sudden if subito) accent.
