or KS, is a German honorific title for distinguished singers of opera and classical music.
Historically, the title was bestowed by princes or kings, when it was styled Hofkammersänger(in), where Hof refers to the royal court.
[3] The title is given in Germany and in Austria usually on the recommendation of relevant national and local institutions.
[79] The prerequisite is at least five years of membership in an ensemble at a state theater or regular guest appearances.
[130] The equivalent designation in Sweden and Denmark are respectively hovsångare (male) or hovsångerska (female) and kongelige kammersangere.
