Context: A baritone is a type of classical male singing voice whose vocal range lies between the bass and the tenor voice types.  It is the most common male voice.  Originally from the Greek βαρύτονος ("barýtonos") , meaning "deep (or heavy) sounding", music for this voice is typically written in the range from the second F below middle C to the F above middle C (i.e. F–F) in choral music, and from the second A below middle C to the A above middle C (A to A) in operatic music, but can be extended at either end.  The baritone voice type is generally divided into the baryton-Martin baritone (light baritone), lyric baritone, "Kavalierbariton", Verdi baritone, dramatic baritone, "baryton-noble" baritone, and the bass-baritone. In music, tessitura (] , pl.  "tessiture", "texture"; ) is the most esthetically acceptable and comfortable vocal range for a given singer or, less frequently, musical instrument; the range in which a given type of voice presents its best-sounding (or characteristic) timbre.  This broad definition is often interpreted to refer specifically to the pitch range that most frequently occurs within a given part of a musical piece.  Hence, in musical notation, "tessitura" is the ambitus in which that particular vocal (or less often instrumental) part lies—whether high or low, etc. The contralto voice in opera and classical music has a range which typically lies between the F below middle C (F3) to two Fs above middle C (F5).  In the lower and upper extremes, some contralto voices can sing from the E below middle C (E3) to two B♭ s above middle C (B♭ 5).  The contralto voice has the lowest tessitura of the female voices and is noted for its rich and deep vocal timbre.  True operatic contraltos are very rare.  The following is a list of contralto singers who have regularly performed unamplified classical or operatic music in concert halls and/or opera houses. A dramatic soprano is a type of operatic soprano with a powerful, rich, emotive voice that can sing over, or cut through, a full orchestra.  Thicker vocal folds in dramatic voices usually (but not always) mean less agility than lighter voices but a sustained, fuller sound.  Usually this voice has a lower tessitura than other sopranos, and a darker timbre.  They are often used for heroic, often long-suffering, tragic women of opera.  Dramatic sopranos have a range from approximately low A (A) to "high C" (C).  Some dramatic sopranos, known as Wagnerian sopranos, have an exceptionally big voice that can assert itself over a large orchestra (of more than 80 or even 100 pieces).  These voices are substantial, often denser in tone, extremely powerful and, ideally, evenly balanced throughout the vocal registers. Wagnerian sopranos usually play mythic heroines.  Successful Wagnerian sopranos are rare and often Wagnerian roles are performed by Italianate dramatic sopranos. Vocal weight refers to the perceived "lightness" or "heaviness" of a singing voice.  This quality of the voice is one of the major determining factors in voice classification within classical music.  Lighter voices are often associated with the term "lyric" and are usually brighter and more agile; heavier voices are often associated with the term "dramatic" and are usually powerful, rich, and darker.  Other voice types like the spinto have a more medium vocal weight.  Vocal weight can also affect overall vocal agility; heavier voices often have more difficulty maneuvering through florid coloratura passages than their lighter counterparts, as their weight and power compromises agility.  Likewise, dramatic roles are often written with larger orchestras in mind as dramatic voices can carry more easily over larger ensembles. A voice type is a particular human singing voice identified as having certain qualities or characteristics of vocal range, vocal weight, tessitura, vocal timbre, and vocal transition points ("passaggio"), such as breaks and lifts within the voice.  Other considerations are physical characteristics, speech level, scientific testing, and vocal register.  A singer's voice type is identified by a process known as voice classification, by which the human voice is evaluated and thereby designated into a particular voice type.  The discipline of voice classification developed within European classical music and is not generally applicable to other forms of singing.  Voice classification is often used within opera to associate possible roles with potential voices.  Several different voice classification systems are available to identify voice types, including the German "Fach" system and the choral music system among many others; no system is universally applied or accepted. The bass singing voice has a vocal range that lies around the second E below middle C to the E above middle C (i.e., E–E).  As with the contralto singing voice being the rarest female voice type, the bass voice is the rarest for males, and has the lowest vocal range of all voice types.  However, the bass voice is determined not only by its vocal range, but also by its timbre, which tends to be darker than that of a baritone voice. A Heldenbaritone is an opera singer, a German dramatic baritone. A bass ( ) is a type of classical male singing voice and has the lowest vocal range of all voice types.  According to "The New Grove Dictionary of Opera", a bass is typically classified as having a vocal range extending from around the second E below middle C to the E above middle C (i.e., E–E).  Its tessitura, or comfortable range, is normally defined by the outermost lines of the bass clef.  Categories of bass voices vary according to national style and classification system.  Italians favour subdividing basses into the "basso cantante" (singing bass), "basso buffo" ("funny" bass), or the dramatic "basso profondo" (low bass).  The American system identifies the bass-baritone, comic bass, lyric bass, and dramatic bass.  The German "fach" system offers further distinctions: Spielbass (Bassbuffo), Schwerer Spielbass (Schwerer Bassbuffo), Charakterbass (Bassbariton), and Seriöser Bass.  These classification systems can overlap.  Rare is the performer who embodies a single "fach" without also touching repertoire from another category. A bass-baritone is a high-lying bass or low-lying "classical" baritone voice type which shares certain qualities with the true baritone voice.  The term arose in the late 19th century to describe the particular type of voice required to sing three Wagnerian roles: the Dutchman in "Der fliegende Holländer", Wotan/Der Wanderer in the "Ring Cycle" and Hans Sachs in "Die Meistersinger von Nürnberg".  Wagner labelled these roles as "Hoher Bass" ("high bass")—see fach for more details.
