Enrico Caruso began as a lyrical tenor in the late 19th and the first several years of the 20th century (the lyrical tenor voice is relatively light as compared to “heavier” voices). His voice, however, became deeper, more powerful and resonant as his career unfolded. When he reached full artistic and tonal maturity toward his mid to late forties (1913-20), his new “dramatic tenor” voice caused both amazement and controversy. How could Caruso’s voice resemble a baritone’s in both its color and energetic substance, yet could also have, when artistically required, the range, agility, and smooth, silken finish of a highly polished lyrical tenor?
