"In the last century, everybody was singing lower"

This quote by Placido Domingo is referring to the development of singing styles over the previous century. In the early 1900s, singers were known for their lower singing variety and making use of a more classical design of singing. This style was frequently described as "bel canto" and was identified by a smooth, lyrical noise. As time progressed, vocalists began to try out different singing strategies and styles, leading to a more varied range of singing styles. This shift in singing designs has been attributed to the influence of jazz, rock, and popular song. As an outcome, vocalists today are able to reach greater notes and use a larger range of singing techniques. This quote by Placido Domingo is a pointer of how far singing designs have actually come in the last century, and just how much more diverse and expressive they have actually become.
