Gioachino Rossini embodied quite well the ideals of the Restoration, at least in the choice of traditional and already tested subjects. Yet, on the other side, his music was completely revolutionary for its novelty: rhythmic energy, robust orchestral texture, dynamic melodies are some of the elements of his new style.
La Sonnambula was a complete triumph, since its premiere. The newspapers wrote of “a melody that goes to the heart, an instrumentation always beautiful and well built” and reported of “endless applauses”. The story revolves around the character of Amina, the archetypal of the slandered innocent.
Everywhere in the world, Italian language is popular thanks to music; not just Opera but also pop hits such as Volare or Mamma. Common Italian words are increasingly used in other languages while notation on music scores is traditionally in Italian (piano, forte, crescendo, rallentando etc…). So much so that many Italian terms used for music are now truly international, representing a substantial part of the international Italian vocabulary.
