Trivia: Which European orchestra never appoints a principal conductor?
Bavarian Radio Symphony
The correct answer is Vienna Philharmonic
So why is this answer correct? : The Vienna Philharmonic Orchestra is almost 200 years old and, unlike most other orchestras, does not use a consistent conductor. The intention is to keep the control in the hands of the musicians, rather than a single leader. The orchestra is known for its high-pitched sound and for having some more unconventional instruments, like the Vienna horn and Weiner oboe.
