Rossini intended Rosina's voice as contralto, but the fabric, ornaments, colors, and vocal ambitus allow the sopranos to approach it. Nowadays, the rossinian contralto voices, which represented the authentic terminology of the times, are rarer. Contralto rossinian, like all the voices of Italian melodrams from the beginning of the century, is expressed by standard or recitative musical, cabaret and aria, with a dramatic composition of very precise characters. The recitatives in Sevilla's Barber of Opera by Gioacchino Rossini are also reference music pages that we will analyze.
