This post shows the technical term VERDI BARITONE explained in a few sentences with links to practical examples.
The absence of a tenor protagonist and whose role is filled by a baritone. This role develops great dramatic power and requires high vocal flexibility for passages in higher registers. Verdi has often composed for this baritone type (Nabucco, Simon Boccanegra, Macbeth etc.).
