RFZ music, also known as "Restricted Frequency Zone" music, holds significance in the contemporary music scene due to its unique sound and experimental nature. It pushes boundaries by exploring unconventional frequencies and sonic textures, creating a new and innovative listening experience for audiences. This genre challenges traditional music norms and offers a fresh perspective on sound production and composition.

The corresponding Italian musical term would be "con forza" - literally "with force" - though in a piece of music you would more likely see the word "sforzato". A single note, played with force would be marked "sforzando", while the musical direction "rfz" (short for "rinforzando", placed in the same manner as a lettered dynamic marking such as "p" or "f") would indicate an entire passage played with force.
The S means subito which in Italian means suddenly and the p means piano which means soft. The z is wrong. So it is either Spp which means suddenly soft or sfz which is a subito fortepiano which means a sudden accent immediately followed by piano (soft). There is also rfz which is rinforzando indicating that several notes, or a short phrase, are to be emphasized.
