Opera is an art form in which singers and musicians perform a
dramatic work combining text (libretto) and musical score, usually in
a theatrical setting. Opera incorporates many of the elements of
spoken theatre, such as acting, scenery, and costumes and sometimes
includes dance. The performance is typically given in an opera house,
accompanied by an orchestra or smaller musical ensemble. Opera
singing is unique in the vocal world.
Opera is a high energy form of singing, with huge physical requirements, involving projecting the voice to the back of a theatre, over an orchestra and without any amplification. Opera singers therefore have to undergo specific training - often taking years - to ensure they can meet these demands.
Hence, weather you want to become a professional opera singer or you just want to sing as a hobby, practicing the art of opera can improve your singing voice. Learning and perfecting any skill requires a lot of practice, but the results will be worth all of the hard work you put into learning to sing opera.
