Kammersänger
Kammersänger (male) or Kammersängerin (female) (German pronunciation: [ˈkamɐˌzɛŋɐ, -ˌzɛŋəʁɪn]; abbreviated Ks. or KS) is a German honorific title for distinguished singers of opera and classical music.[1][2] It literally means "chamber singer". 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.[3] In East Germany, some concert halls bestowed this designation.
