, )—with several similar constructions (, , , pronounced in American English as )—is a term with several meanings that relate to Italian singing, and whose definitions have often been misunderstood. Bel canto was not only seen as a vocal technique, but also as a source of national pride for Italians, specifically in how the musical qualities aligned with their identity. However, this pride was often complicated by political circumstances.

The phrase was not associated with a school of singing until the middle of the 19th century, when writers in the early 1860s used it nostalgically to describe a manner of singing that had begun to wane around 1830. Nonetheless, "neither musical nor general dictionaries saw fit to attempt [a] definition [of bel canto] until after 1900". The term remains vague and ambiguous in the 21st century and is often used to evoke a lost singing tradition.

History of the term and its various definitions

As generally understood today, the term bel canto refers to the Italian-originated vocal style that prevailed throughout most of Europe during the 18th and early 19th centuries. Late 19th- and 20th-century sources "would lead us to believe that bel canto was restricted to beauty and evenness of tone, legato phrasing, and skill in executing highly florid passages, but contemporary documents [those of the late 18th and early 19th centuries] describe a multifaceted manner of performance far beyond these confines". The main features of the bel canto style were:

The phrase "bel canto" was not commonly used until the latter part of the 19th century, when it was set in opposition to the development of a weightier, more powerful style of speech-inflected singing associated with German opera and, above all, Richard Wagner's revolutionary music dramas. Wagner (1813–1883) decried the Italian singing model, alleging that it was concerned merely with "whether that G or A will come out roundly". He advocated a new, Germanic school of singing that would draw "the spiritually energetic and profoundly passionate into the orbit of its matchless Expression."

French musicians and composers never embraced the more florid extremes of the 18th-century Italian bel canto style. They disliked the castrato voice and because they placed a premium on the clear enunciation of the texts of their vocal music, they objected to the sung word being obscured by excessive fioritura.

The popularity of the bel canto style as espoused by Rossini, Donizetti and Bellini faded in Italy during the mid-19th century. It was overtaken by a heavier, more ardent, less embroidered approach to singing that was necessary to perform the innovative works of Giuseppe Verdi (1813–1901) with maximum dramatic impact. Tenors, for instance, began to inflate their tone and deliver the high C (and even the high D) directly from the chest rather than resorting to a suave head voice/falsetto as they had done previously – sacrificing vocal agility in the process. Sopranos and baritones reacted in a similar fashion to their tenor colleagues when confronted with Verdi's drama-filled compositions. They subjected the mechanics of their voice production to greater pressures and cultivated the exciting upper part of their respective ranges at the expense of their mellow but less penetrant lower notes. Initially at least, the singing techniques of 19th-century contraltos and basses were less affected by the musical innovations of Verdi, which were built upon by his successors Amilcare Ponchielli (1834–1886), Arrigo Boito (1842–1918) and Alfredo Catalani (1854–1893).

Detractors

One reason for the eclipse of the old Italian singing model was the growing influence within the music world of bel cantos detractors, who considered it to be outmoded and condemned it as vocalization devoid of content. To others, however, bel canto became the vanished art of elegant, refined, sweet-toned musical utterance. Rossini lamented in a conversation that took place in Paris in 1858 that: "Alas for us, we have lost our bel canto". Similarly, the so-called German style was as derided as much as it was heralded. In the introduction to a collection of songs by Italian masters published in 1887 in Berlin under the title Il bel canto, Franz Sieber wrote: "In our time, when the most offensive shrieking under the extenuating device of 'dramatic singing' has spread everywhere, when the ignorant masses appear much more interested in how loud rather than how beautiful the singing is, a collection of songs will perhaps be welcome which – as the title purports – may assist in restoring bel canto to its rightful place." It has come to be a generally recognised thing that voice, pure and simple, by its very composition, or "placing", interferes with the organs of speech; making it impossible for a vocalist to preserve absolute purity of pronunciation in song as well as in speech. It is because of this view that the principle of "vocalising" words, instead of musically "saying" them, crept in, to the detriment of vocal art. This false position is due to the idea that the 'Arte del bel-canto' encouraged mere sensuous beauty of voice, rather than truth of expression."
