Abstract
The idea that classical singers should join the notes of the vocal line by maintaining a consistent vocal colour is a relatively recent historical construct. In the last decades of the nineteenth century, singers in the Italian tradition were loyal to a very different vocal aesthetic, which valued the distinct differences in timbre between different vocal registers, as this article shows through a comparative analysis of pedagogical writing and pre-1925 recordings. The latter reveal that, in the early twentieth century, old and new techniques for uniting the vocal registers coexisted, and reflected an aesthetic transition towards a more gendered quality of the operatic voice. This process was intertwined with profound transformations in Italian operatic culture. The demands of a new realistic idiom known as verismo required a new type of vocalism, which prompted singers to re-conceive the 'art of vocal registration'.
