full_context: Document 1: Mezzo-soprano: A mezzo-soprano or mezzo ( , ; ] meaning "half soprano") is a type of classical female singing voice whose vocal range lies between the soprano and the contralto voice types. The mezzo-soprano's vocal range usually extends from the A below middle C to the A two octaves above (i.e. A–A in scientific pitch notation, where middle C = C). In the lower and upper extremes, some mezzo-sopranos may extend down to the F below middle C (F) and as high as "high C" (C).
Document 2: Voice type: 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.
Document 3: Tenor: Tenor is a type of classical male singing voice whose vocal range is between the countertenor and baritone voice types. The tenor's vocal range (in choral music) lies between C, the C one octave below middle C, and A, the A above middle C. In solo work, this range extends up to C, or "tenor high C". The low extreme for tenors is roughly A♭ (two A♭ s below middle C). At the highest extreme, some tenors can sing up to two Fs above middle C (F).
Document 4: Vocal weight: 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.
Document 5: Bass (voice type): 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.
Document 6: Siegfried Lorenz: Siegfried Lorenz (born 1945) is a German opera and concert singer. A baritone, he is particularly noted for his recordings of the lieder of Franz Schubert. He was the first to be appointed a permanent soloist at the Leipzig Gewandhaus.
Document 7: Dramatic soprano: 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.
Document 8: Adolf Robinson: Adolf Robinson (1838–1920) was an Austrian baritone who had a major opera career during the second half of the 19th century. His extensive stage repertoire contained numerous Wagnerian roles such as Wotan in "The Ring Cycle" and Hans Sachs in "Die Meistersinger von Nürnberg". Other highlights of his career included the title characters in Rossini's "William Tell", Mozart's "Don Giovanni", Verdi's "Rigoletto", Hérold's "Zampa", and Heinrich Marschner's "Der Templer und die Jüdin".
Document 9: Soprano: A soprano ] is a type of classical female singing voice and has the highest vocal range of all voice types. The soprano's vocal range (using scientific pitch notation) is from approximately middle C (C) = 261 Hz to "high A" (A) =880 Hz in choral music, or to "soprano C" (C, two octaves above middle C) =1046 Hz or higher in operatic music. In four-part chorale style harmony, the soprano takes the highest part, which usually encompasses the melody.

Document 12: Baritone: 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.
Document 13: Bernhard Bötel: Bernhard Bötel (1883–1953) was a German operatic tenor and actor who had an active career in Germany and Austria during the first half of the 20th century. He made recordings for several record labels during the early years of the recording industry, including His Master's Voice, Odeon Records, Polydor Records, Tri-Ergon, and Vox Records. On the stage he sang a variety of roles in operas and operettas from leading parts to comprimario roles. His stage repertoire included Belmonte in Wolfgang Amadeus Mozart's "Die Entführung aus dem Serail", Chapelou in Adolphe Adam's "Le postillon de Lonjumeau", Count Almaviva in Gioachino Rossini's "The Barber of Seville", Daniel in Franz Lehár's "The Merry Widow", the Duke of Mantua in Giuseppe Verdi's "Rigoletto", Gabriel von Eisenstein in Johann Strauss II's "Die Fledermaus", Indigo in Strauss' "Indigo und die vierzig Räuber", Jeník in Bedřich Smetana's "The Bartered Bride", Paolino in Domenico Cimarosa's "Il matrimonio segreto", Pâris in Jacques Offenbach's "La belle Hélène", Pietro in Franz von Suppé's "Boccaccio", and Wilhelm Meister in Ambroise Thomas' "Mignon".
Document 14: Bass-baritone: 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.
Document 15: Lyric soprano: A lyric soprano is a type of operatic soprano voice that has a warm quality with a bright, full timbre that can be heard over an orchestra. The lyric soprano voice generally has a higher tessitura than a soubrette and usually plays ingenues and other sympathetic characters in opera. Lyric sopranos have a range from approximately middle C (C4) to "high D" (D6). This is the most common female singing voice. There is a tendency to divide lyric sopranos into two groups, light and full.
