A coloratura soprano is a type of operatic soprano voice that specializes in music that is distinguished by agile runs, leaps and trills.
The term coloratura refers to the elaborate ornamentation of a melody, which is a typical component of the music written for this voice. Within the coloratura category, there are roles written specifically for lighter voices known as lyric coloraturas and others for larger voices known as dramatic coloraturas. Some roles may be sung by either voice. For example, Donizetti's Lucia di Lammermoor was famously done at the Metropolitan Opera for many years by lyric coloratura Lily Pons, whose voice was quite small and light, but more recently the same role was sung there by Ruth Ann Swenson whose voice is larger and duskier, and even more dramatic by Maria Callas who has cast a long shadow. Categories within a certain vocal range are determined by the size, weight and color of the voice.
A very agile light voice with a high upper extension, capable of fast vocal coloratura. Lyric coloraturas have a range of approximately middle C (C4) to "high F" (F6). Such a soprano is sometimes referred to as a soprano leggero if her vocal timbre has a slightly warmer quality. The soprano leggero also typically does not go as high as other coloraturas, peaking at a "high E" (E6).Bel canto roles were typically written for this voice, and a wide variety of other composers have also written coloratura parts. Baroque music, early music and baroque opera also have many roles for this voice.
A coloratura soprano with great flexibility in high-lying velocity passages, yet with great sustaining power comparable to that of a full spinto or dramatic soprano. Dramatic coloraturas have a range of approximately "low B" (B3) to "high F" (F6). Various dramatic coloratura roles have different vocal demands for the singer – for instance, the voice that can sing Abigail (Nabucco, Verdi) is unlikely to also sing Lucia (Lucia di Lammermoor, Donizetti), but a factor in common is that the voice must be able to convey dramatic intensity as well as flexibility. Roles written specifically for this kind of voice include the more dramatic Mozart and bel canto female roles and early Verdi. This is a rare vocal fach, as thick vocal cords are needed to produce the large, dramatic notes, which usually lessens the flexibility and acrobatic abilities of the voice. One notable performer, who had excelled at this particular repertoire in the 20th century, was Maria Callas, a soprano sfogato, convincing in both dramatic and lyric coloratura soprano roles.
