Other forms: sforzandos
A note or chord that is played sforzando can have a surprise effect on the listener, because it is played with a sudden, strong accent, louder than the notes or chords around it.
Sforzando is actually a contraction of subito forzando, meaning "suddenly forceful" in Italian. It can be used as an adverb, adjective, or noun, and is usually represented by the symbol sfz in sheet music. The sound of a sforzando note or chord can be similar to one played marcato, as both will stand out from the surrounding notes. However, a marcato note is usually short, while a sforzando note must be held for its full length even though the loudness quickly fades.
