Although many physical therapists practice in hospitals, more than 80% practice in other settings. Acute Care - In this setting, physical therapy is provided to individuals who are admitted to a hospital for short-term patient care for reasons such as illness, surgery, accident, or recovery from a trauma.
In an opera, the beginning of an orchestral piece is called an overture. Other orchestral performances don't have a special name for the beginning.
Euridice (1600) is the first surviving opera. The libretto was by Rinuccini, music by Peri, with some portions by Caccini. This was also significant in that it used recitative, a foundation of operatic storytelling. But--what was the first great opera? My vote is for Monteverdi's Orfeo, libretto by Striggio, premiered in 1607.
