How is sforzato played?

Give the marked note or chord a sharp, forceful emphasis distinct from the prevailing dynamic, normally without extending that force across an unmarked passage. Sources frequently treat sforzato and sforzando as near-synonyms, so no universal audible distinction is imposed; both derive from Italian sforzare, to force. The marking remains local, while rinforzando can be used for reinforcement whose span is decided separately by context. Use sf or sfz with awareness that both forms also occur under sforzando; do not infer fz, which the notation manual assigns more precisely to forzando/forzato.

How does sforzato sound?

A single forced, accented attack that stands out sharply from the notes around it.

In context

Duden, the historical Grove dictionary and Essential Dictionary of Music Notation directly support sf for sforzato; Duden, OnMusic, Grove and Essential support sfz. The same sources document practical overlap with sforzando rather than a stable one-to-one spelling rule. fz belongs more directly to forzando/forzato, and sffz is an intensified compound. The forceful single-event function remains, while the earlier unqualified inclusion of fz is narrowed.
