Which technique must the modern virtuoso singer be able to perform?

Answer 1

The modern virtuoso singer must be able to perform many techniquest, but vibrato certainly springs to mind to name one. There are of course way too many to name. Dynamic control, articulation (especially a good legato line), strong resonance etc. etc.

Answer 2

A modern virtuoso is someone who is a master at his or her craft, someone whose vocal skills are superior to most other singers. This is often the result of having God-given talent but also the result of spending long hours in practice-- training the voice to bring out the best in it, mastering breathing techniques, and developing skills as a performer, in order to make the lyrics of a song come alive. A virtuoso singer must have excellent range (able to hit high notes as well as low notes), and a voice that is able to express the emotions of the song naturally without seeming forced. The singing virtuoso is familiar with, and comfortable with, all of the songs in his or her repertoire, but is not afraid of a challenge and is not afraid to master a new song or a new operatic role.
