The incorporation of digital tools into the traditional singing studio is a con-troversial topic, especially in the context of classical singing. Classical vocal pedagogy requires the direct contact between teacher and student, particular-ly in the early phases of vocal development, to ensure that proper technique is acquired by the student and healthy vocal production is established. Fur-thermore, aspects of vocal emission such as colour, brilliance, and dynamics are strongly influenced by the performance venue, since classical singing does not typically use microphones to augment sound. Moreover, there is al-so the issue of preserving a centuries-old legacy, as attested by vocal treatises dating back to the 17th century. The present study was motivated by the in-creased use of online platforms in the process of vocal education. This raised the question: to what extent can the teaching process benefit from the use of video conferencing tools that require the use of microphones, given that the quality of sung tones is altered when sound waves are converted into electri-cal signals? Furthermore, the authors observed that certain digital tools have been specifically designed to help singers warm up or improve their intona-tion, prompting inquiry into how these emerging tools might impact classical vocal pedagogy.
