The Fach System

Operatic voices can be classified by a variety of means. At base we define singers by the vocal range of their voice (basically what notes they can sing), but opera has developed a range of conventions for grouping singers with particular vocal styles as well. The German Fach system is the predominant one and the one we cover here. This system gets pretty specific so frequently singers will sing across the sub-classifications, for example, a singer might sing a lyric tenor role one month and a spinto tenor one the next.

Overview

The soprano range

The soprano is the highest female voice type and they often take the leading female role. The vocal range for an operatic soprano is roughly from middle C up to the C two octaves above, though plenty of music particularly for coloratura sopranos ascends even further.

Sopranos are split into five major categories:

Coloratura

The coloratura soprano is capable of seemingly superhuman feats. The voice is extremely agile, firing out fast paced coloratura sections that ascend as high as the 3rd F above middle C (and in a few cases even higher). These roles have existed from Baroque through 20th Century opera. A particularly fine example is Lucia in Donizetti’s Lucia di Lammermoor and an excerpt from her mad scene can be found below.

Soubrette

A soubrette soprano refers as much to an archetype of character as a voice type. These are cheeky, coquettish parts, sung by singers with sweet, bright voices. The tessitura of these parts can sometimes be pretty high but without an excess of coloratura.

Lyric

The lyric soprano usually possesses a fuller, richer sound than the soubrette and tends to have a more mature quality. Their tessitura generally lies higher than the soubrette but lower than the coloratura heading up to the D two octaves and a tone above middle C on occasion. Some of the loveliest music is given to these singers, Liu gets this haunting tune near the end of Turandot

Spinto

The spinto soprano gets a good deal of the really plum roles in opera, particularly in the Italian Romantic tradition of Verdi and Puccini. Partly for this reason, lyric and dramatic sopranos frequently take on these roles whether naturally suited or not (and more than a few lyric sopranos have shortened their careers by taking on heavy spinto roles). These roles call for the light, brilliant high notes of the lyric soprano but with more heft in the big climaxes (spinto translates as "pushed"). Below you’ll find an excerpt from Tatyana’s passionate love letter scene from Eugene Onegin.

Dramatic

These are big soprano voices with sufficient heft to be heard over a large orchestra whilst maintaining an evenness across the full range. Dramatic soprano roles came to the fore in the Romantic era, indeed there are few genuine dramatic soprano roles before the mid-19th Century. Wagner supplied a range of dramatic soprano roles such as the colossal part that is Brunnhilde. Below is a tiny clip of Christine Brewer singing the immolation scene from the conclusion of Wagner's Ring Cycle

Mezzo-Soprano

The Mezzo-Soprano range

Singing slightly lower than the soprano, the vocal range of an operatic mezzo-soprano (often abbreviated to just mezzo) spans from the G below middle C to the A two octaves above, though plenty of roles require the voice to stretch above and/or below this.

Mezzos are too often relegated to supporting roles or villains. What principal roles exist for the mezzo-soprano are most commonly found in French-language operas, Bizet’s Carmen probably the most famous mezzo role of them all.

Mezzos breakdown into three broad categories:

Coloratura

The coloratura mezzo-soprano is a fairly small niche. Two periods heavily used this voice type and one of these after the fact. Roles actually written for agile, lower female voices belong to the Bel Canto period, Donizetti and Rossini writing a range of big roles. The other collection of coloratura mezzo roles were originally written for castrati in the Baroque period but, as we no longer abide by such practices, mezzos have frequently taken these parts in modern times.

Coloratura mezzo roles require agile runs up to even high C but also call for just as much oompf in the middle and bottom of the mezzo’s range. Below you’ll find a brief excerpt from Rossini’s Il Barbiere di Sivilia, with Agnes Baltsa singing “Una voce poco fa”, a wonderful example of this sort of singer.

Lyric

The lyric mezzo-sprano gets perhaps the least glamorous of roles, a good whack of them are “trouser” parts (women playing men). That classification belies voices that are also normally smooth and rather sexy such as Dorabella in Mozart’s Cosi Fan Tutte. Here's a brief clip from Ann Murray singing "È amore un ladroncello" from that very opera:

Dramatic

Frequently playing mothers or witches, the dramatic mezzo voice is warm, rich and unbeatably loud. This voice type was frequently called for from the middle 1800s onwards. Verdi wrote a whole host of dramatic mezzo roles as did Wagner. One of the most vivid can be found in Richard Strauss’s Elektra: the role of Klytemnestra.

Countertenor

Standard countertenor range on a keyboard
The Countertenor range

The highest male voice type, roughly equivilent in pitch to mezzo-sopranos. Countertenors were popular in the 17th Century but fell out of fashion until the the mid 20th Century roughly coinciding with a boom in the popularity of Baroque and other early music. The countertenor range is roughly from the G below middle C to a high F one octave above middle C. These male singers achieve this high lying range through the use of their head voice (often called falsetto).

In opera countertenors largely take Baroque roles, particularly those originally given to Castrati. This voice type has been seized upon by some modern composers however, and has been increasingly utilised in contemporary opera, most famously by Britten with the King of the Fairies, Oberon, in A Midsummer Night's Dream

Tenor

The Tenor range

Tenors frequently take the leading male role (and are said to always get the girl, on stage and off!). The operatic vocal range for a tenor is roughly from the C below middle C to the C above middle C.

Striking these high Cs is a challenge for many tenors and one of the pinnacles of high C singing comes in Donizetti’s La Fille du Regiment, in the aria "Ah! mes amis, quel jour de fête!", a clip of which you can hear below.

"Ah! mes amis" sung by Juan Diego Florez

Tenors breakdown into a range of categories, some more common than others. Below are the four of the most common groupings:

Lyric

Warm, bright and capable of hitting the highest tenor notes with ease, lyric tenors get some of the most charming operatic roles. A fairly broad category, these singers can range in tonal colour, some much darker and fuller with others lighter and brighter. Below is a short excerpt from the prologue of Les Contes d’Hoffmann by Offenbach. It's sung by Rolando Villazón who sits at the heavier end of the lyric tenor spectrum.

Spinto

Similar to the lyric tenor in range but with more heft, particularly towards the top. These roles are far tougher than many people give them credit for, the heroic Verdi parts icebergs that many a tenor have crashed upon. Radames from Verdi's Aida is one such role and “Celeste Aida” a formidable challenge.

"Celeste Aida" sung by Placido Domingo

Dramatic

Big, emotive and powerful, a dramatic tenor is usually spared the blushes of trying to hit a string of high notes but must project a rich sound against potent orchestral forces. The example below is from Verdi's Otello, a dark brooding anti-hero requiring a muscular sound like that of Jon Vickers.

Heldentenor

Literally translates as heroic tenor. This is a vocal class largely introduced by Wagner, a collection of parts with low, almost baritonal, tessitura. They are massive roles, requiring the singer sustain a powerful sound over enormously long periods making them near unsingable. Wagner created a good dozen of these roles but perhaps the most demanding of all is Siegfried in the Ring Cycle. Here is a short excerpt from a scene in which Siegfried forges his sword (hence the banging).

Baritone

The Baritone range

The middle male voice singing in the range from roughly the second G below middle C up to the G above it.

Lyric

Singing in a range from the A one and a half octaves below middle C to the A just above it, the lyric baritone is a light, fruity deep male voice. These tend towards comic parts but they’re not without depth in some cases. Papageno in Mozart’s Die Zauberflote (The Magic Flute to most people) gets this delightful aria about his dream woman!

"Ein Mädchen oder Weibchen"s sung by Stephan Degout

Verdi

The Verdi baritone as you might expect from the name is a voice type specific to Verdi operas. True Verdi baritones are somewhat rare, the roles requiring the singer sing notes at the extremes of both ends of the baritone range and do so with a wealth of round sound. Verdi took Shakespeare's Macbeth and made a riveting opera out of it, the title role a great example of the Verdi baritone.

"Pieta, rispeto, amore" from Macbeth sung by leo Nucci

Dramatic

The lowest true baritonal vocal type, dramatic baritones have a similar range to the Verdi singers, the G two octaves below middle C upwards, but the tessitura tends to lie lower. The despicable Scarpia from Puccini’s Tosca is a prime example of this voice, here is a clip of Bryn Terfel singing the mighty Te Deum.

Bass

The Bass range

The lowest voice of all. The standard operatic bass range is from the E above middle C to the E two octaves below. Some bass singers can go even lower, though this is seldom called for in the standard bass repertoire.

Bass-baritone

The bass-baritone can sing as low as a bass but just as comfortably in higher lying tessitura close to the baritone range. This voice type was predominantly written for from the mid 19th Century onwards but several Mozart roles, written in the era before baritone had even become a vocal type, are commonly given to singers in this class. Here is an excerpt from Strauss's Salome, the great Hans Hotter as Jokanaan

Buffo

Buffo bass roles are funny, comic relief, roles found most frequently in Bel Canto works. They are very distinct parts with extensive “patter” singing requirements, the text frequently a tongue-twisting nightmare of alliteration.

Though amusing, these are often villainous roles, albeit hopeless, blustering ones, for example Doctor Magnifico in Rossini’s La Cenerentola.

"Sia qualunque delle figlie" sung by Alessandro Corbelli

Basso profundo

The lowest voice type in opera is the basso profundo. These singers produce a wall of rich, unending sound with limited vibrato but enormous power. The parts are mostly limited to older male villains though not exclusively, for example Sarastro in Mozart’s Die Zauberflöte, who is a sage like leader.
