Nothing strikes the ear quite like a soprano singing in the sonic stratosphere. Whether thrilling, chilling, or repellent to the listener, the reaction to cascades of coloratura with climaxing high notes is strong. Coloratura-agile, rapid-fire singing-was originally essential for all singers, but its function changed greatly when it became the specialty of particular sopranos over the course of the nineteenth century.The central argument of Vocal Virtuosity challenges the historical commonplace that coloratura became an anachronism in nineteenth-century opera. Instead, the book demonstrates that melismas at mid-century were made modern. Coloratura became an increasingly marked musical gesture during the century with a correspondingly more specific dramaturgical function. In exploring this transformation, the book reveals the instigators of this change in vocal practice and examines the historical traces of Parisian singers who were the period's greatest exponents of vertiginous vocality as archetypes of the modern coloratura soprano. The book constructs the historical trajectory of coloratura as it became gendered the provenance of the female singer, while also considering what melismas can signify in operatic performance. As a whole, it argues that vocal virtuosity was a source of power for women, generating space for female authorship and creativity. In so doing, the book reclaims a place in history for the coloratura soprano.
