Bel Canto Vocal Studio

Musicologists occasionally apply the label bel canto technique to the arsenal of virtuosic vocal accomplishments and concepts imparted by singing teachers to their students during the late 18th century and the early 19th century. Many of these teachers were castrati.

"All [their] pedagogical works follow the same structure, beginning with exercises on single notes and eventually progressing to scales and improvised embellishments," writes Potter on p. 47 of his Tenor: History of a Voice. "The really creative ornamentation required for cadenzas, involving models and formulae that could generate newly improvised material, came towards the end of the process." (Today's pervasive idea that singers should refrain from improvising and always adhere strictly to the letter of a composer's published score is a comparatively recent phenomenon, promulgated during the first decades of the 20th century by dictatorial conductors such as Arturo Toscanini [1867-1957], who championed the dramatic operas of Verdi and Wagner and believed in keeping performers on a tight interpretive leash. See, for instance, Volume 1 of Michael Scott's survey The Record of Singing [Duckworth, London, 1977], pp. 135–136; also Potter, p. 77.)

Potter notes, however, that as the 19th century unfurled, "The general tendency ... was for singers not to have been taught by castrati (there were few of them left) and for serious study to start later, often at one of the new conservatories rather than with a private teacher. The traditional techniques and pedagogy were still acknowledged, but the teaching was generally in the hands of tenors and baritones who were by then at least once removed from the tradition itself."

Early 19th-century teachers described the voice as being made up of three registers. The chest register was the lowest of the three and the head register the highest, with the passaggio in between. These registers needed to be smoothly blended and fully equalized before a trainee singer could acquire total command of his or her natural instrument, and the surest way to achieve this outcome was for the trainee to practise vocal exercises assiduously. Bel canto-era teachers were great believers in the benefits of vocalise and solfeggio. They strove to strengthen the respiratory muscles of their pupils and equip them with such time-honoured vocal attributes as "purity of tone, perfection of legato, phrasing informed by eloquent portamento, and exquisitely turned ornaments", to quote from the introduction to Volume 2 of Scott's The Record of Singing (Duckworth, London, 1979).

Major refinements occurred to the existing system of voice classification during the 19th century as the international operatic repertoire diversified, split into distinctive nationalist schools and expanded in size. Whole new categories of singers such as mezzo-soprano and Wagnerian bass-baritone arose towards the end of the 19th century, as did such new sub-categories as lyric coloratura soprano, dramatic soprano and spinto soprano, and various grades of tenor, stretching from lyric through spinto to heroic. These classificatory changes have had a lasting effect on the way singing teachers designate voices and the way in which opera house managements cast their productions.

It would be wrong, however, to think that there was across-the-board uniformity among 19th-century bel canto adherents when it came to passing on their knowledge and instructing students. Each of them had their own training regimes and pet notions; but, fundamentally, they all subscribed to the same set of bel canto precepts, and the exercises that they devised in order to enhance their students' breath support, dexterity, range and technical control remain valuable and, indeed, are still employed by some teachers.
