We usually think of music as entertainment, but in the ancient world, music was often considered a form of medicine. Over the past few decades, scientists have rediscovered music’s healing abilities, and studies have shown that music can effectively treat conditions such as schizophrenia, depression, chronic pain, Parkinson’s, PTSD, autism, help stroke patients recover, and more.
Rossini wrote his first opera, Demetrio e Polibio in 1806 not even fifteen. His official debut was in Venice in 1810 with the opera La Cambiale di Matrimonio. In the following two decades Rossini composed 39 operas, 4 or 5 new ones per year, with some controversial premieres, such as the Barber of Seville legendary fiasco in Rome in 1816 and some extraordinary successes: La Gazza Ladra, Zelmira and Semiramide, the last opera premiered in Italy in 1823.
Operatic voices are divided into 4 categories: soprano (high female), alto (low female), tenor (high male) and bass (low male). There are also 2 intermediate voices: mezzo soprano, female voice and baritone, male voice between tenor and bass. There are many more subtle distinctions used to define the range, tone, colour and timbre of a voice. They developed as a consequence of increasingly demanding roles which required more specific vocal types.
