In the absence of a mid-century Italian source on singing as comprehensive as Tosi’s Opinioni of 1723, the music itself can provide clues to the evolution of vocal technique. In order to accommodate the wider ranges, singers likely used more than one vocal register. Falsetto and head voice would have been necessary to achieve the upper extension of the range. For female singers, head voice alone may have sufficed, though there is nothing from a laryngeal point of view to have precluded the use of falsetto at any point in the range.41 Tosi is the first source to discuss this issue, though it is unclear whether his equation of voce di testa with falsetto extends to all voice types.42 We can only surmise how smoothly blended was the transition between registers before the end of the seventeenth century. It was certainly of the utmost importance to Tosi, who preferred head voice for executing passaggi and other ornaments. A blended register transition still did not mean that the Italians preferred a unified color to the voice; composers exploited the contrasts between the top and bottom. Like pop singers today, Italian Baroque singers were adept at switching between different registers, laying the foundation for the cantar di sbalzo techniques so essential
