Brilliant, showy skill in performing something very difficult — and the difficulty has to show. It started in music, where a bravura passage is one written to let a singer or player display technique, and it still lives mostly in reviews of music, dance, acting, and sometimes writing or sport. It is used as a noun ('a display of bravura', 'played with great bravura') and, more often in English, before another noun as an adjective: 'a bravura performance', 'a bravura solo', 'a bravura piece of filmmaking'. The word is admiring, but it carries a small hint of showing off; a critic who calls a performance 'bravura' means it was dazzling, not that it was tender or deep. It is a formal, literary word — you would meet it in a newspaper review, not in conversation with friends.
