Frederick II was one of the most fascinating figure in medieval history. His power was immense: King of Sicily and Jerusalem, Emperor of the Romans, King of Italy and Germany. His kingdom extended from the northern sea to Sicily and, on the east, to Israel and Lebanon.
The protagonists of romantic operas live love differently than those of the eighteenth-century repertoire. For them love is a complete emotional enrapture. They share this incontrollable passion with a public who generally has a more ordinary life and now, through this new music drama, can experience a total emotional involvement.
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.
