In Ancient Greece and Rome there was a specific term for a building where musical competitions took place: ᾨδεῖον. It is important, of course, to keep in mind that musical contests were a very important part of their musical culture, as evidenced, for instance, in Virgil's Eclogues. The word Odeon has since been used in the names of some prominent musical buildings: Hammersmith Odeon, Odeon theater (several places in different countries use this name), Odeon Marble Arch etc. If you happen to have a magnificent room or structure dedicated to music, Odeon or Odeum (the Latin form of the same word) can be a very classy name to refer to it.
