Fach

The German Fach system (German pronunciation: [fax]; literally "compartment" or "subject of study", here in the sense of "vocal specialization") is a method of classifying singers, primarily opera singers, according to the range, weight, and color of their voices.

It is used worldwide, but primarily in Europe, especially in German-speaking countries and by repertory opera houses.

Opera companies keep lists of available singers by Fach so that when they are casting roles for an upcoming production, they do not inadvertently contact performers who would be inappropriate for the part.

[2] Below is a list of Fächer (German pronunciation: [ˈfɛçɐ]), their ranges as written on sheet music, and roles generally considered appropriate to each.

Roles like Norma, Lady Macbeth, Odabella or Abigaille are good examples of Italian roles that are not necessarily a coloratura soprano (even though the score calls for coloratura singing), but a full bodied dramatic soprano with a voice that can handle extreme dramatic singing and that is flexible enough to sing coloratura.
