This is a question regarding how good someone is at performing music, Jazz in particular. During most jazz performances, one or more members of the group will step forward and start to play by themselves--soloing--and will play their instrument to the best of their ability for a minute or so, demonstrating their "virtuosity" i.e., how good they are, by playing an "improvisational passage"--creating new music on the spot that usually sounds similar to the basic theme of the song.
The extended virtuosic section for a soloist in a concerto is called a cadenza.
Some popular solo piano jazz pieces that showcase virtuosity and improvisational skills include "Take Five" by Dave Brubeck, "Round Midnight" by Thelonious Monk, and "Blue Rondo la Turk" by Dave Brubeck. These pieces feature complex rhythms, intricate melodies, and opportunities for the pianist to demonstrate their technical prowess and creativity through improvisation.
The free solo passage without orchestral accompaniment in a concerto is called a cadenza.
Usually just the solo, but a showier passage with little or no backing is a 'cadenza'.

Cadenza
It is called a CADENZA where the soloist shows their virtuosity. In the Baroque and early Classical period, soloists were free to make up their own cadenzas but later on Composers began writing them out.
The cadenza in a sonata performance is a solo section where the performer can showcase their skill and creativity. It allows the musician to improvise and add their personal touch to the piece, demonstrating their virtuosity and musical interpretation.
That can describe a passage of music that is played at a very highly skilled and musical level or any other artistic pursuit.
"Han Solo. I'm captain of the Millenium Falcon. Chewie here tells me you're looking for passage to the Alderaan system."
Soloist composition is often referred to as "concerto" when it features a solo instrument accompanied by an orchestra. In this format, the soloist typically showcases their virtuosity and interpretive skills through a series of contrasting movements. Other forms that highlight a soloist include "sonata" and "solo suite," particularly in chamber music contexts.
The word "concerto" originates from the Italian word "concertare," which means "to bring into agreement." In music, a concerto is a composition for a solo instrument or instruments accompanied by an orchestra. The term typically refers to a piece where the soloist(s) and orchestra engage in a musical dialogue, showcasing the skills and virtuosity of the solo performer(s) against the backdrop of the orchestral accompaniment.
