concoctor การใช้

• In his essay " A Communication to My Friends " in 1851, Wagner claimed that " The Dutchman " represented a new start for him : " From here begins my career as poet, and my farewell to the mere concoctor of opera-texts . " Indeed, to this day the opera is the earliest of Wagner's works to be performed at the Bayreuth Festival, and, at least for that theatre, marks the start of the mature Wagner canon.
