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.
The soprano range
The soprano is the highest female voice type and they often take the leading female role. The vocal range
operatic soprano is roughly from middle C up to the C two octaves above, though plenty of music
coloratura sopranos ascends even further.
Sopranos are split into five major categories:
The coloratura soprano is capable of seemingly superhuman feats. The voice is extremely agile, firing out
paced coloratura sections that ascend as high as the 3rd F above middle C (and in a few cases even
These roles have existed from Baroque through 20th Century opera. A particularly fine example is Lucia
Donizetti’s Lucia di Lammermoor and an excerpt from her mad scene can be found below.

A soubrette soprano refers as much to an archetype of character as a voice type. These are cheeky,
parts, sung by singers with sweet, bright voices. The tessitura of these parts can sometimes be pretty
without an excess of coloratura.
An excerpt from Hansel und Gretel sung by Diana Damrau
The lyric soprano usually possesses a fuller, richer sound than the soubrette and tends to have a more
quality. Their tessitura generally lies higher than the soubrette but lower than the coloratura heading
the D two octaves and a tone above middle C on occasion. Some of the loveliest music is given to these

The spinto soprano gets a good deal of the really plum roles in opera, particularly in the Italian
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
shortened their careers by taking on heavy spinto roles). These roles call for the light, brilliant high
of the lyric soprano but with more heft in the big climaxes (spinto translates as "pushed"). Below

These are big soprano voices with sufficient heft to be heard over a large orchestra whilst maintaining
evenness across the full range. Dramatic soprano roles came to the fore in the Romantic era, indeed
few genuine dramatic soprano roles before the mid-19th Century. Wagner supplied a range of dramatic
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

The Mezzo-Soprano range
Singing slightly lower than the soprano, the vocal range of an operatic mezzo-soprano (often abbreviated
mezzo) spans from the G below middle C to the A two octaves above, though plenty of roles require the
stretch above and/or below this.
Mezzos are too often relegated to supporting roles or villains. What principal roles exist for the
are most commonly found in French-language operas, Bizet’s Carmen probably the most famous mezzo
The Habanera from Carmen sung by Elina Garanca
Mezzos breakdown into three broad categories:
The coloratura mezzo-soprano is a fairly small niche. Two periods heavily used this voice type and one of
after the fact. Roles actually written for agile, lower female voices belong to the Bel Canto period,
and Rossini writing a range of big roles. The other collection of coloratura mezzo roles were originally
for castrati in the Baroque period but, as we no longer abide by such practices, mezzos have frequently
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
and bottom of the mezzo’s range. Below you’ll find a brief excerpt from Rossini’s Il Barbiere di
with Agnes Baltsa singing “Una voce poco fa”, a wonderful example of this sort of singer.
"Una voce poco fa" from Il Barbiere di Sivilia sung by Agnes Baltsa
The lyric mezzo-sprano gets perhaps the least glamorous of roles, a good whack of them are “trouser”
playing men). That classification belies voices that are also normally smooth and rather sexy such as
in Mozart’s Cosi Fan Tutte. Here's a brief clip from Ann Murray singing "È amore un ladroncello"
that very opera:
"È amore un ladroncello" from Cosi Fan Tutte sung by Ann Murray
Frequently playing mothers or witches, the dramatic mezzo voice is warm, rich and unbeatably loud. This
voic 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

The Countertenor range
The highest male voice type, roughly equivilent in pitch to mezzo-sopranos. Countertenors were popular in
17th Century but fell out of fashion until the the mid 20th Century roughly coinciding with a boom in
popularity of Baroque and other early music. The countertenor range is roughly from the G below middle C
high F one octave above middle C. These male singers achieve this high lying range through the use of
voice (often called falsetto).
In opera countertenors largely take Baroque roles, particularly those originally given to Castrati. This
type has been seized upon by some modern composers however, and has been increasingly utilised in
opera, most famously by Britten with the King of the Fairies, Oberon, in A
Midsummer Night's Dream
Oberon's "I know a bank" sung by Jochen Kowalski
The Tenor range
Tenors frequently take the leading male role (and are said to always get the girl, on stage and off!).
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
Donizetti’s La Fille du Regiment, in the aria "Ah! mes amis, quel jour de fête!", a clip of which

Tenors breakdown into a range of categories, some more common than others. Below are the four of the most
Warm, bright and capable of hitting the highest tenor notes with ease, lyric tenors get some of the most
operatic roles. A fairly broad category, these singers can range in tonal colour, some much darker and
with others lighter and brighter. Below is a short excerpt from the prologue of Les Contes
Offenbach. It's sung by Rolando Villazón who sits at the heavier end of the lyric tenor spectrum.
Hoffmann sung by Rolando Villazón
Similar to the lyric tenor in range but with more heft, particularly towards the top. These roles are far
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
Big, emotive and powerful, a dramatic tenor is usually spared the blushes of trying to hit a string of
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.
The start of "Niun mi tema" sung by John Vickers
Literally translates as heroic tenor. This is a vocal class largely introduced by Wagner, a collection of
with low, almost baritonal, tessitura. They are massive roles, requiring the singer sustain a powerful
over enormously long periods making them near unsingable. Wagner created a good dozen of these roles but
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).

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
baritone range and do so with a wealth of round sound. Verdi took Shakespeare's Macbeth and made
riveting opera out of it, the title role a great example of the Verdi baritone.
"Pieta, rispeto, amore" from Macbeth sung by leo Nucci
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
Tosca is a prime example of this voice, here is a clip of Bryn Terfel
singing the mighty Te Deum.

The Bass range
The lowest voice of all. The standard operatic bass range is from the E above middle C to the E two
below. Some bass singers can go even lower, though this is seldom called for in the standard bass
The bass-baritone can sing as low as a bass but just as comfortably in higher lying tessitura close to
baritone range. This voice type was predominantly written for from the mid 19th Century onwards but
Mozart roles, written in the era before baritone had even become a vocal type, are commonly given to
this class. Here is an excerpt from Strauss's Salome, the great Hans Hotter as Jokanaan

Buffo bass roles are funny, comic relief, roles found most frequently in Bel Canto works. They are very
parts with extensive “patter” singing requirements, the text frequently a tongue-twisting nightmare of
Though amusing, these are often villainous roles, albeit hopeless, blustering ones, for example Doctor
in Rossini’s La Cenerentola.

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