Concert sites are places where musical performances take place. These can range from large ARENAS with thousands of seats to smaller halls and odea, which are more intimate VENUES. An arena is a large enclosed area that can accommodate a large number of people, typically used for sports or concerts. A hall is a large room used for meetings, concerts, or other events. An odeon is a small theater or concert hall, usually seating fewer than 500 people. A venue is a location where an event such as a concert or a play takes place.
