The Fach system: voice types for opera singers explained

Fach is the system opera houses use to match a voice to a role. Companies keep lists of singers by Fach for casting¹, and in German theaters the Fach in your contract can oblige you to sing a role⁴. This page is part of the roles section.

What Fach means

Fach means compartment or subject of study¹. It is a method of classifying singers, primarily opera singers, according to the range, weight and color of their voices¹. It is used worldwide, but primarily in Europe, especially in German-speaking countries and by repertory opera houses¹. The German Fach system is the predominant one in opera³. It was created in the mid-19th century to aid in the casting process for opera houses⁶. A Fach works as a reference point for recognizing voice types by drama, size and range⁷.

Voice type is the broader idea. A voice type is a classification of the human singing voice into perceivable categories or groups². A singer’s voice type is identified by a process known as voice classification², which also considers physical characteristics, speech level and scientific testing². Voice classification is a tool for singers, composers, venues and listeners to categorize vocal properties and to associate roles with voices². No system is universally applied or accepted².

Why opera houses use it

Fach prevents singers from being asked to sing roles they are incapable of performing¹. Opera companies keep lists of available singers by Fach for use when they cast roles for an upcoming production¹.

In German theaters the label is part of the contract. Fach is incorporated into singers’ contracts and can be binding on both parties⁴. If a role is in a Fach listed in your contract, you can be obligated to sing it⁴. The system reflects and shapes how German theaters cast roles⁴.

The fest system explains the weight of the label. In most German, Austrian and Swiss houses, singers are contracted to work in the same ensemble for 1 to 2 years⁶. Hires sing all the parts in their Fach, whether or not they feel it is an appropriate fit⁶. The total number of Fächer is approximately 23⁶. The system was never fully adopted in North America or outside Europe, and singers in America are rarely contracted to one company for an entire season⁶.

The Handbuch der Oper

The reference that assigns roles to Fächer is the Handbuch der Oper, which assigns roles to a Fach and names the kind of voice that should sing them⁴. It is generally referred to as Kloiber, after its original author, Rudolf Kloiber⁴. The German vocal model is outlined in Kloiber’s Handbuch der Oper⁷. Kloiber split the voices into 6 divisions: soprano, mezzo-soprano, alto, tenor, baritone and bass⁷.

The Bärenreiter edition is edited by Wulf Konold, Rudolf Kloiber and Robert Maschka⁵. It is a hardcover with German text, ISBN 9783761823231, 958 pages⁵. It includes an index of Fachpartien, titles, composers and librettists, and over 100 new opera portraits from the early Baroque to the present⁵.

Later Kloiber editions often collapsed Fächer into one Fach, which obliged singers to sing more roles⁴. At Texas Christian University, a voice professor reports that few of the young undergraduate students know the Fach system⁷.

How Kloiber sorts the Fächer

Kloiber’s Fächer fall into two broad categories, Seriöser and Spiel- und Charakter⁴. Seriöser Fächer are defined by vocal beauty, quality, power and expressiveness⁴. Spiel- und Charakter Fächer are defined by a physical, brilliant presence, acting and characterization⁴. Casting in the second group also turns on physical type: several agents told the OperGermany author that singers in these Fächer cannot get hired if they do not match it⁴. The system rests on long practice in theaters with 10-month seasons, many premieres and constant rehearsals⁴.

Kloiber combines the role lists of the dramatic mezzo and dramatic alto, since very few theaters have more than one soloist covering these roles⁴. Pedrillo’s aria “Frisch zum Kampfe” is an essential audition aria for the buffo tenor because it shows high notes⁴.

The lyric tenor Fach shows how Fächer merged: its singers are expected to sing Riccardo in Un ballo in maschera and the Duca in Rigoletto⁴. Some Fächer have grown very broad⁴. A true dramatic coloratura is much sought after, but hitting all the notes does not mean the voice has the power⁴.

The basic voice groups

Women are typically divided into three groups: soprano, mezzo-soprano and contralto². Men are usually divided into four groups: countertenor, tenor, baritone and bass². When the pre-pubescent male voice is counted as an eighth term, treble can be applied².

The typical soprano voice lies between C4 (middle C) and C6². The mezzo-soprano voice lies between the soprano and contralto voices, overlapping both². What principal roles exist for the mezzo-soprano are most commonly found in French-language operas, and Bizet’s Carmen is probably the most famous mezzo role of them all³. See the Carmen guide for that score. Mezzos are too often relegated to supporting roles or villains³.

Soprano subcategories

Sopranos are often broken down into five subcategories: coloratura soprano, soubrette, lyric soprano, spinto soprano and dramatic soprano². The German names refine that list.

Most sopranos start out as soubrettes, changing Fach as the voice matures¹. Dramatic soprano roles came to the fore in the Romantic era³.

Dramatic coloratura

Violetta in La traviata and the Queen of the Night are more traditionally dramatic coloratura roles, but it is difficult to find a dramatic coloratura¹. For that reason these roles are often sung by a lyric coloratura¹. Imogene, Leonora and Violetta require a dramatic soprano voice, most often a dramatic soprano with an agile voice that can easily produce coloratura and high notes¹.

Lyric coloratura singers must do fast acrobatics with easy high notes¹. Dramatic coloratura singers must also do fast vocal acrobatics and reach high notes, such as the F6 of the Queen of the Night¹. The Mozartian and Italian dramatic coloratura sopranos are different: a singer of Konstanze, Donna Anna or Fiordiligi cannot necessarily sing the Italian dramatic coloratura parts¹. The Queen of the Night can make a career almost on that single role alone⁴. If you are working on Violetta, read the La traviata guide.

Mezzo and contralto

Coloratura mezzo roles are found especially in Rossini’s operas, and they were originally written for altos with agility and secure top notes¹. The coloratura mezzo-soprano is a fairly small niche³. Many lyric mezzos make the transition to singing as sopranos at some point in their careers¹. A dramatic mezzo concentrates on the middle and low registers¹.

The contralto is the lowest of the female voices and by far the rarest³. A true operatic contralto is rare, and roles for contraltos are often sung by mezzo-sopranos². The same holds in the Fach list: the dramatischer Alt (dramatic contralto), a deep, penetrating low female voice with a darker, richer sound than a typical alto, is a very rare Fach¹. Many mezzos have tried these roles, yet real altos fare better¹. A true Ulrica or Erde is rare, so the slightly higher dramatic alto most often covers these roles⁴. The coloratura contralto is exceedingly rare, but blessed with several significant parts³. The tiefer Alt, the deep contralto, is a low female voice¹ with a full and dense sound and great depth in the lower register⁷.

The limits of the system

Some roles can be sung by more than one Fach, and many singers do not easily fit into a Fach¹. Some sopranos may sing both Koloratursopran and Dramatischer Koloratursopran roles¹. Singers often sing across the sub-classifications³. Some Fächer cover so many roles that one singer is unlikely to be able to do them all⁴.

Most individuals possess medium voices⁸. Many singers incorrectly classify their own voices, assuming that because they cannot sing high notes they must be of a lower Fach⁸. Although all voices within the same Fach have common characteristics, each sub-type has unique features that require a particular approach in teaching⁸. A singer should never be forced or encouraged to train as a voice type that the instrument is not naturally suited for⁸.

How to use your Fach

Learn the Fach system so that you can use it but not be limited by it⁴. Three habits:

• Do not sing beyond your Fach in an audition. Singing beyond your Fach will quickly disqualify you from being considered⁴. Build your audition package inside your Fach.
• Expect to try roles before you are cast. Very often the theater will ask you to try the role with its top coach⁴.
• Check the contract. In German houses the Fach in your contract decides which roles you can be obliged to sing⁴.
