Philharmonic hall seating plan

"A concert hall is a cultural building which serves as a performance venue, chiefly for classical instrumental music. Many concert halls exist as one of several halls or performance spaces within a larger performing arts center and, where appropriate, the name of the arts centre is included.
Many larger cities have both public and private concert halls. Particularly in smaller cities with fewer alternative venues, concert halls may also be used to accommodate other activities, from rock concerts to university graduation ceremonies, in addition to their primary purpose.
This list does not include other venues such as sports stadia or convention centres which may occasionally be used for concerts." [List of concert halls. Wikipedia]
